-.Ft double

-.Ft long double

-.Sh DESCRIPTION
-The
-.Fn atan2 ,
-.Fn atan2f ,
-and
-.Fn atan2l
-functions compute the principal value of the arc tangent of
-.Fa y/ Ns Ar x ,
-using the signs of both arguments to determine the quadrant of
-the return value.
-.Pp
-The
-.Fn carg ,
-.Fn cargf ,
-and
-.Fn cargl
-functions compute the complex argument (or phase angle) of
-.Fa z .
-The complex argument is the number theta such that
-.Li z = r * e^(I * theta) ,
-where
-.Li r = cabs(z) .
-The call
-.Li carg(z)
-is equivalent to
-.Li atan2(cimag(z), creal(z)) ,
-and similarly for
-.Fn cargf
-and
-.Fn cargl .
-.Sh RETURN VALUES
-The
-.Fn atan2 ,
-.Fn atan2f ,

-functions, if successful,
-return the arc tangent of
-.Fa y/ Ns Ar x
-in the range

-.It Ta
-.Pf sign( Ar y Ns )*\*(Pi/2 Ta
-if
-.Ar x
-= 0 \(!=
-.Ar y .
-.El
-.Sh NOTES
-The function
-.Fn atan2
-defines "if x > 0,"
-.Fn atan2 0 0
-= 0 despite that previously
-.Fn atan2 0 0
-may have generated an error message.
-The reasons for assigning a value to
-.Fn atan2 0 0
-are these:
-.Bl -enum -offset indent
-.It
-Programs that test arguments to avoid computing
-.Fn atan2 0 0
-must be indifferent to its value.
-Programs that require it to be invalid are vulnerable
-to diverse reactions to that invalidity on diverse computer systems.
-.It
-The
-.Fn atan2
-function is used mostly to convert from rectangular (x,y)
-to polar
-.if n\
-(r,theta)
-.if t\
-(r,\(*h)
-coordinates that must satisfy x =
-.if n\
-r\(**cos theta
-.if t\
-r\(**cos\(*h
-and y =
-.if n\
-r\(**sin theta.
-.if t\
-r\(**sin\(*h.
-These equations are satisfied when (x=0,y=0)
-is mapped to
-.if n \
-(r=0,theta=0).
-.if t \
-(r=0,\(*h=0).
-In general, conversions to polar coordinates
-should be computed thus:
-.Bd -unfilled -offset indent
-.if n \{\
-r	:= hypot(x,y);  ... := sqrt(x\(**x+y\(**y)
-theta	:= atan2(y,x).
-.\}
-.if t \{\
-r	:= hypot(x,y);  ... := \(sr(x\u\s82\s10\d+y\u\s82\s10\d)
-\(*h	:= atan2(y,x).
-.\}
-.Ed
-.It
-The foregoing formulas need not be altered to cope in a
-reasonable way with signed zeros and infinities
-on a machine that conforms to
-.Tn IEEE 754 ;
-the versions of
-.Xr hypot 3
-and
-.Fn atan2
-provided for
-such a machine are designed to handle all cases.
-That is why
-.Fn atan2 \(+-0 \-0
-= \(+-\*(Pi
-for instance.
-In general the formulas above are equivalent to these:
-.Bd -unfilled -offset indent
-.if n \
-r := sqrt(x\(**x+y\(**y); if r = 0 then x := copysign(1,x);
-.if t \
-r := \(sr(x\(**x+y\(**y);\0\0if r = 0 then x := copysign(1,x);

-Generally speaking, infinities, zeroes and \*(Nas are handled as would

-= 0 regardless of the value of

-.Fn cexp "-\*(If + I*y"
-= 0 and
-.Fo creal
-.Fn cexp "\*(If + I*y" Fc
-= \*(If
-for any
-.Fa y
-(even though the latter property is only mathematically true for

-.Sh NOTES
-The function
-.Fn pow x 0
-returns x**0 = 1 for all x including x = 0, \*(If, and \*(Na .
-Previous implementations of pow may
-have defined x**0 to be undefined in some or all of these

-Here are reasons for returning x**0 = 1 always:
-.Bl -enum -width indent
-.It
-Any program that already tests whether x is zero (or
-infinite or \*(Na) before computing x**0 cannot care
-whether 0**0 = 1 or not.
-Any program that depends
-upon 0**0 to be invalid is dubious anyway since that
-expression's meaning and, if invalid, its consequences
-vary from one computer system to another.
-.It
-Some Algebra texts (e.g.\& Sigler's) define x**0 = 1 for
-all x, including x = 0.
-This is compatible with the convention that accepts a[0]
-as the value of polynomial
-.Bd -literal -offset indent
-p(x) = a[0]\(**x**0 + a[1]\(**x**1 + a[2]\(**x**2 +...+ a[n]\(**x**n
-.Ed
-.Pp
-at x = 0 rather than reject a[0]\(**0**0 as invalid.
-.It
-Analysts will accept 0**0 = 1 despite that x**y can
-approach anything or nothing as x and y approach 0
-independently.
-The reason for setting 0**0 = 1 anyway is this:
-.Bd -ragged -offset indent
-If x(z) and y(z) are
-.Em any
-functions analytic (expandable
-in power series) in z around z = 0, and if there
-x(0) = y(0) = 0, then x(z)**y(z) \(-> 1 as z \(-> 0.
-.Ed
-.It
-If 0**0 = 1, then
-\*(If**0 = 1/0**0 = 1 too; and
-then \*(Na**0 = 1 too because x**0 = 1 for all finite
-and infinite x, i.e., independently of x.

-include those described in

-On some architectures, raising an overflow or underflow exception
-also causes an inexact exception to be raised.
-In these cases, the overflow or underflow will be raised first.
-.Pp
-The
-.Fn fegetexceptflag
-and
-.Fn fesetexceptflag
-routines are preferred to
-.Fn fetestexcept
-and
-.Fn feraiseexcept ,
-respectively, for saving and restoring exception flags.
-The latter do not re-raise exceptions and may preserve
-architecture-specific information such as addresses where
-exceptions occurred.
-.Sh RETURN VALUES
-The
-.Fn feclearexcept ,
-.Fn fegetexceptflag ,
-.Fn feraiseexcept ,
-and
-.Fn fesetexceptflag
-functions return 0 upon success, and non-zero otherwise.
-The
-.Fn fetestexcept
-function returns the bitwise OR of the values of the current exception
-flags that were requested.

-.Ft int
-.Fn fegetexcept void
-.Sh DESCRIPTION
-The
-.In fenv.h
-routines manipulate the floating-point environment,
-which includes the exception flags and rounding modes defined in
-.St -ieee754 .
-.Ss Exceptions
-Exception flags are set as side-effects of floating-point arithmetic
-operations and math library routines, and they remain set until
-explicitly cleared.
-The following macros expand to bit flags of type
-.Vt int
-representing the five standard floating-point exceptions.
-.Bl -tag -width ".Dv FE_DIVBYZERO"
-.It Dv FE_DIVBYZERO
-A divide-by-zero exception occurs when the
-.Em exact
-result of a computation is infinite (according to the limit definition).
-For example, dividing a finite non-zero number by zero or computing
-.Fn log 0
-raises a divide-by-zero exception.
-.It Dv FE_INEXACT
-An inexact exception is raised whenever there is a loss of accuracy
-due to rounding.
-.It Dv FE_INVALID
-Invalid operation exceptions occur when a program attempts to
-perform calculations for which there is no reasonable representable
-answer.
-For instance, subtraction of like-signed infinities, division of zero by zero,
-ordered comparison involving \*(Nas, and taking the real square root of a
-negative number are all invalid operations.
-.It Dv FE_OVERFLOW
-In contrast with divide-by-zero,
-an overflow exception occurs when an infinity is produced because
-the magnitude of the exact result is
-.Em finite
-but too large to fit in the destination type.
-For example, computing
-.Li DBL_MAX * 2
-raises an overflow exception.
-.It Dv FE_UNDERFLOW
-Underflow occurs when the result of a computation loses precision
-because it is too close to zero.
-The result is a subnormal number or zero.
-.El
-.Pp
-Additionally, the
-.Dv FE_ALL_EXCEPT
-macro expands to the bitwise OR of the above flags and any
-architecture-specific flags.
-Combinations of these flags are passed to the
-.Fn feclearexcept ,
-.Fn fegetexceptflag ,
-.Fn feraiseexcept ,
-.Fn fesetexceptflag ,
-and
-.Fn fetestexcept
-functions to clear, save, raise, restore, and examine the
-processor's floating-point exception flags, respectively.
-.Pp
-Exceptions may be
-.Em unmasked
-with
-.Fn feenableexcept
-and masked with
-.Fn fedisableexcept .
-Unmasked exceptions cause a trap when they are produced, and
-all exceptions are masked by default.
-The current mask can be tested with
-.Fn fegetexcept .
-.Ss Rounding Modes
-.St -ieee754
-specifies four rounding modes.
-These modes control the direction in which results are rounded
-from their exact values in order to fit them into binary
-floating-point variables.
-The four modes correspond with the following symbolic constants.
-.Bl -tag -width ".Dv FE_TOWARDZERO"
-.It Dv FE_TONEAREST
-Results are rounded to the closest representable value.
-If the exact result is exactly half way between two representable
-values, the value whose last binary digit is even (zero) is chosen.
-This is the default mode.
-.It Dv FE_DOWNWARD
-Results are rounded towards negative \*[If].
-.It Dv FE_UPWARD
-Results are rounded towards positive \*[If].
-.It Dv FE_TOWARDZERO
-Results are rounded towards zero.
-.El
-.Pp
-The
-.Fn fegetround
-and
-.Fn fesetround
-functions query and set the rounding mode.
-.Ss Environment Control
-The
-.Fn fegetenv
-and
-.Fn fesetenv
-functions save and restore the floating-point environment,
-which includes exception flags, the current exception mask,
-the rounding mode, and possibly other implementation-specific
-state.
-The
-.Fn feholdexcept
-function behaves like
-.Fn fegetenv ,
-but with the additional effect of clearing the exception flags and
-installing a
-.Em non-stop
-mode.
-In non-stop mode, floating-point operations will set exception flags
-as usual, but no
-.Dv SIGFPE
-signals will be generated as a result.
-Non-stop mode is the default, but it may be altered by
-.Fn feenableexcept
-and
-.Fn fedisableexcept .
-The
-.Fn feupdateenv
-function restores a saved environment similarly to
-.Fn fesetenv ,
-but it also re-raises any floating-point exceptions from the old
-environment.
-.Pp
-The macro
-.Dv FE_DFL_ENV
-expands to a pointer to the default environment.
-.Sh EXAMPLES
-The following routine computes the square root function.
-It explicitly raises an invalid exception on appropriate inputs using
-.Fn feraiseexcept .
-It also defers inexact exceptions while it computes intermediate
-values, and then it allows an inexact exception to be raised only if
-the final answer is inexact.

-.Sh CAVEATS
-The FENV_ACCESS pragma can be enabled with
-.Dl "#pragma STDC FENV_ACCESS ON"
-and disabled with the
-.Dl "#pragma STDC FENV_ACCESS OFF"
-directive.
-This lexically-scoped annotation tells the compiler that the program
-may access the floating-point environment, so optimizations that would
-violate strict IEEE-754 semantics are disabled.
-If execution reaches a block of code for which
-.Dv FENV_ACCESS
-is off, the floating-point environment will become undefined.
-.Sh BUGS
-The
-.Dv FENV_ACCESS
-pragma is unimplemented in the system compiler.
-However, non-constant expressions generally produce the correct
-side-effects at low optimization levels.

-the final result.
-.Pp
-For instance, the expression
-.No "1.2e100 * 2.0e208 - 1.4e308"
-produces \*(If due to overflow in the intermediate product, whereas
-.No "fma(1.2e100, 2.0e208, -1.4e308)"
-returns approximately 1.0e308.
-.Pp
-The fused multiply-add operation is often used to improve the
-accuracy of calculations such as dot products.
-It may also be used to improve performance on machines that implement
-it natively.
-The macros
-.Dv FP_FAST_FMA ,
-.Dv FP_FAST_FMAF
-and
-.Dv FP_FAST_FMAL
-may be defined in
-.In math.h
-to indicate that
-.Fn fma ,
-.Fn fmaf ,
-and
-.Fn fmal
-(respectively) have comparable or faster speed than a multiply
-operation followed by an add operation.
-.Sh IMPLEMENTATION NOTES
-In general, these routines will behave as one would expect if
-.No "x * y + z"
-were computed with unbounded precision and range,
-then rounded to the precision of the return type.
-However, on some platforms, if
-.Fa z
-is \*(Na, these functions may not raise an exception even
-when the computation of
-.No "x * y"
-would have otherwise generated an invalid exception.
-.Sh SEE ALSO
-.Xr fenv 3 ,
-.Xr math 3
-.Sh STANDARDS
-The
-.Fn fma ,
-.Fn fmaf ,
-and
-.Fn fmal
-functions conform to
-.St -isoC-99 .
-A fused multiply-add operation with virtually identical
-characteristics appears in IEEE draft standard 754R.
-.Sh HISTORY
-The
-.Fn fma
-and
-.Fn fmaf
-routines first appeared in
-.Fx 5.4 ,
-and
-.Fn fmal
-appeared in
-.Fx 6.0 .

-.Nd IEEE standard 754 for floating-point arithmetic
-.Sh DESCRIPTION
-The IEEE Standard 754 for Binary Floating-Point Arithmetic
-defines representations of floating-point numbers and abstract
-properties of arithmetic operations relating to precision,
-rounding, and exceptional cases, as described below.
-.Ss IEEE STANDARD 754 Floating-Point Arithmetic
-Radix: Binary.
-.Pp
-Overflow and underflow:
-.Bd -ragged -offset indent -compact
-Overflow goes by default to a signed \*(If.
-Underflow is
-.Em gradual .
-.Ed
-.Pp
-Zero is represented ambiguously as +0 or \-0.
-.Bd -ragged -offset indent -compact
-Its sign transforms correctly through multiplication or
-division, and is preserved by addition of zeros
-with like signs; but x\-x yields +0 for every
-finite x.
-The only operations that reveal zero's
-sign are division by zero and
-.Fn copysign x \(+-0 .
-In particular, comparison (x > y, x \(>= y, etc.)\&
-cannot be affected by the sign of zero; but if
-finite x = y then \*(If = 1/(x\-y) \(!= \-1/(y\-x) = \-\*(If.
-.Ed
-.Pp
-Infinity is signed.
-.Bd -ragged -offset indent -compact
-It persists when added to itself
-or to any finite number.
-Its sign transforms
-correctly through multiplication and division, and
-(finite)/\(+-\*(If\0=\0\(+-0
-(nonzero)/0 = \(+-\*(If.
-But
-\*(If\-\*(If, \*(If\(**0 and \*(If/\*(If
-are, like 0/0 and sqrt(\-3),
-invalid operations that produce \*(Na. ...
-.Ed
-.Pp
-Reserved operands (\*(Nas):
-.Bd -ragged -offset indent -compact
-An \*(Na is
-.Em ( N Ns ot Em a N Ns umber ) .
-Some \*(Nas, called Signaling \*(Nas, trap any floating-point operation
-performed upon them; they are used to mark missing
-or uninitialized values, or nonexistent elements
-of arrays.
-The rest are Quiet \*(Nas; they are
-the default results of Invalid Operations, and
-propagate through subsequent arithmetic operations.
-If x \(!= x then x is \*(Na; every other predicate
-(x > y, x = y, x < y, ...) is FALSE if \*(Na is involved.
-.Ed
-.Pp
-Rounding:
-.Bd -ragged -offset indent -compact
-Every algebraic operation (+, \-, \(**, /,
-\(sr)
-is rounded by default to within half an
-.Em ulp ,
-and when the rounding error is exactly half an
-.Em ulp
-then
-the rounded value's least significant bit is zero.
-(An
-.Em ulp
-is one
-.Em U Ns nit
-in the
-.Em L Ns ast
-.Em P Ns lace . )
-This kind of rounding is usually the best kind,
-sometimes provably so; for instance, for every
-x = 1.0, 2.0, 3.0, 4.0, ..., 2.0**52, we find
-(x/3.0)\(**3.0 == x and (x/10.0)\(**10.0 == x and ...
-despite that both the quotients and the products
-have been rounded.
-Only rounding like IEEE 754 can do that.
-But no single kind of rounding can be
-proved best for every circumstance, so IEEE 754
-provides rounding towards zero or towards
-+\*(If or towards \-\*(If
-at the programmer's option.
-.Ed
-.Pp
-Exceptions:
-.Bd -ragged -offset indent -compact
-IEEE 754 recognizes five kinds of floating-point exceptions,
-listed below in declining order of probable importance.
-.Bl -column -offset indent "Invalid Operation" "Gradual Underflow"
-.Em "Exception	Default Result"
-Invalid Operation	\*(Na, or FALSE
-Overflow	\(+-\*(If
-Divide by Zero	\(+-\*(If
-Underflow	Gradual Underflow
-Inexact	Rounded value
-.El
-.Pp
-NOTE: An Exception is not an Error unless handled
-badly.
-What makes a class of exceptions exceptional
-is that no single default response can be satisfactory
-in every instance.
-On the other hand, if a default
-response will serve most instances satisfactorily,
-the unsatisfactory instances cannot justify aborting
-computation every time the exception occurs.

-.Ss Additional Information Regarding Exceptions
-.Pp
-For each kind of floating-point exception, IEEE 754
-provides a Flag that is raised each time its exception
-is signaled, and stays raised until the program resets
-it.
-Programs may also test, save and restore a flag.
-Thus, IEEE 754 provides three ways by which programs
-may cope with exceptions for which the default result
-might be unsatisfactory:
-.Bl -enum
-.It
-Test for a condition that might cause an exception
-later, and branch to avoid the exception.
-.It
-Test a flag to see whether an exception has occurred
-since the program last reset its flag.
-.It
-Test a result to see whether it is a value that only
-an exception could have produced.
-.Pp
-CAUTION: The only reliable ways to discover
-whether Underflow has occurred are to test whether
-products or quotients lie closer to zero than the
-underflow threshold, or to test the Underflow
-flag.
-(Sums and differences cannot underflow in
-IEEE 754; if x \(!= y then x\-y is correct to
-full precision and certainly nonzero regardless of
-how tiny it may be.)
-Products and quotients that
-underflow gradually can lose accuracy gradually
-without vanishing, so comparing them with zero
-(as one might on a VAX) will not reveal the loss.
-Fortunately, if a gradually underflowed value is
-destined to be added to something bigger than the
-underflow threshold, as is almost always the case,
-digits lost to gradual underflow will not be missed
-because they would have been rounded off anyway.
-So gradual underflows are usually
-.Em provably
-ignorable.
-The same cannot be said of underflows flushed to 0.
-.El
-.Pp
-At the option of an implementor conforming to IEEE 754,
-other ways to cope with exceptions may be provided:
-.Bl -enum
-.It
-ABORT.
-This mechanism classifies an exception in
-advance as an incident to be handled by means
-traditionally associated with error-handling
-statements like "ON ERROR GO TO ...".
-Different
-languages offer different forms of this statement,
-but most share the following characteristics:
-.Bl -dash
-.It
-No means is provided to substitute a value for
-the offending operation's result and resume
-computation from what may be the middle of an
-expression.
-An exceptional result is abandoned.
-.It
-In a subprogram that lacks an error-handling
-statement, an exception causes the subprogram to
-abort within whatever program called it, and so
-on back up the chain of calling subprograms until
-an error-handling statement is encountered or the
-whole task is aborted and memory is dumped.
-.El
-.It
-STOP.
-This mechanism, requiring an interactive
-debugging environment, is more for the programmer
-than the program.
-It classifies an exception in
-advance as a symptom of a programmer's error; the
-exception suspends execution as near as it can to
-the offending operation so that the programmer can
-look around to see how it happened.
-Quite often
-the first several exceptions turn out to be quite
-unexceptionable, so the programmer ought ideally
-to be able to resume execution after each one as if
-execution had not been stopped.
-.It
-\&... Other ways lie beyond the scope of this document.
-.El
-.Pp
-Ideally, each
-elementary function should act as if it were indivisible, or
-atomic, in the sense that ...
-.Bl -enum
-.It
-No exception should be signaled that is not deserved by
-the data supplied to that function.
-.It
-Any exception signaled should be identified with that
-function rather than with one of its subroutines.
-.It
-The internal behavior of an atomic function should not
-be disrupted when a calling program changes from
-one to another of the five or so ways of handling
-exceptions listed above, although the definition
-of the function may be correlated intentionally
-with exception handling.
-.El
-.Pp
-The functions in
-.Nm libm
-are only approximately atomic.
-They signal no inappropriate exception except possibly ...

-.Sh HISTORY
-A math library with many of the present functions appeared in
-.At v7 .
-The library was substantially rewritten for
-.Bx 4.3
-to provide
-better accuracy and speed on machines supporting either VAX
-or IEEE 754 floating-point.
-Most of this library was replaced with FDLIBM, developed at Sun
-Microsystems, in
-.Fx 1.1.5 .
-Additional routines, including ones for
-.Vt float
-and
-.Vt long double
-values, were written for or imported into subsequent versions of FreeBSD.
-.Sh BUGS
-Some of the
-.Vt "long double"
-math functions in
-.St -isoC-99
-are not available.
-.Pp
-Many of the routines to compute transcendental functions produce
-inaccurate results in other than the default rounding mode.
-.Pp
-On the i386 platform, trigonometric argument reduction is not
-performed accurately for huge arguments, resulting in
-large errors
-for such arguments to
-.Fn cos ,
-.Fn sin ,
-and
-.Fn tan .

-.Sh SYNOPSIS
-.In math.h
-.Ft double
-.Fn nan "const char *s"
-.Ft float
-.Fn nanf "const char *s"
-.Ft long double
-.Fn nanl "const char *s"
-.Sh DESCRIPTION
-The
-.Dv NAN
-macro expands to a quiet \*(Na (Not A Number).
-Similarly, each of the
-.Fn nan ,
-.Fn nanf ,
-and
-.Fn nanl
-functions generate a quiet \*(Na value without raising an invalid exception.
-The argument
-.Fa s
-should point to either an empty string or a hexadecimal representation
-of a non-negative integer (e.g., "0x1234".)
-In the latter case, the integer is encoded in some free bits in the
-representation of the \*(Na, which sometimes store
-machine-specific information about why a particular \*(Na was generated.
-There are 22 such bits available for
-.Vt float
-variables, 51 bits for
-.Vt double
-variables, and at least 51 bits for a
-.Vt long double .
-If
-.Fa s
-is improperly formatted or represents an integer that is too large,
-then the particular encoding of the quiet \*(Na that is returned
-is indeterminate.
-.Sh COMPATIBILITY
-Calling these functions with a non-empty string isn't portable.
-Another operating system may translate the string into a different
-\*(Na encoding, and furthermore, the meaning of a given \*(Na encoding
-varies across machine architectures.
-If you understood the innards of a particular platform well enough to
-know what string to use, then you would have no need for these functions
-anyway, so don't use them.
-Use the
-.Dv NAN
-macro instead.
-.Sh SEE ALSO
-.Xr fenv 3 ,

-.Sh STANDARDS

-functions and the
