(HP Integrity Server Only)
NAME
csinh(), csinhf(), csinhl(), csinhw(), csinhq() - complex hyperbolic sine functions
SYNOPSIS
#include <complex.h>
double complex csinh(double complex z);
float complex csinhf(float complex z);
long double complex csinhl(long double complex z);
extended complex csinhw(extended complex z);
quad complex csinhq(quad complex z);
DESCRIPTION
These functions are available only for Integrity servers.
csinh() returns the complex hyperbolic sine of z.
csinhf() is a float complex version of csinh(); it takes a float complex argument and
returns a float complex result.
csinhl() is a long double complex version of csinh(); it takes a long double complex
argument and returns a long double complex result.
csinhw() is an extended complex version of csinh(); it takes an extended complex argu-
ment and returns an extended complex result.
csinhq() is equivalent to csinhl() on HP-UX systems.
USAGE
To use these functions, compile with the default -Ae option. To use csinhw() or
csinhq(), compile
with the
-fpwidetypes option. Make sure your program includes <complex.h> . Link in the math
library by specifying -lm on the compiler or linker command line.
RETURN VALUE
csinh(conj( z)) = conj(csinh( z)) and csinh is odd.
csinh(+0+i0) returns +0+i0.
csinh(+0+iInf) returns ±0+iNaN (where the sign of the real part of the result is unspecified) and raises
the invalid floating-point exception.
csinh(+0+iNaN) returns ±0+iNaN (where the sign of the real part of the result is unspecified).
csinh(x+iInf) returns NaN+iNaN and raises the invalid floating-point exception, for positive finite x.
csinh(x+iNaN) returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite
nonzero x.
csinh(+Inf+i0) returns +Inf+i0.
csinh(+Inf+iy) returns +Inf(cos(y)+isin(y)), for positive finite y.
csinh(+Inf+iInf) returns ±Inf+iNaN (where the sign of the real part of the result is unspecified) and
raises the invalid floating-point exception.
csinh(+Inf+iNaN) returns ±Inf+iNaN (where the sign of the real part of the result is unspecified).
csinh(NaN+i0) returns NaN+i0.
csinh(NaN+iy) returns NaN+iNaN and optionally raises the invalid floating-point exception, for all
nonzero numbers y.
csinh(NaN+iNaN) returns NaN+iNaN.
ERRORS
No errors are defined.
