csinh(3M)

DESCRIPTION

These functions are available only for IA-64.

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.

USAGE

To use these functions, compile with the default -Ae option. Make sure your program includes <complex.h>. Link in the math library by specifying -lm on the compiler or linker command line.

RETURN VALUES

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.
