NAMEcsinh(), 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); DESCRIPTIONThese 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 argument and returns an extended complex result. csinhq() is equivalent to csinhl() on HP-UX systems. USAGETo 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 VALUEcsinh(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. |
