csinh(), csinhf(), csinhl()

Compute the complex hyperbolic sine

Synopsis:

#include <complex.h>

double complex csinh( double complex z );

float complex csinhf( float complex z );

long double complex csinhl( long double complex z );

Arguments:

z
The value that you want to get the complex hyperbolic sine of.

Library:

libm

Use the -l m option to qcc to link against this library.

Description:

These functions compute the complex hyperbolic sine of the number specified by z.

To check for error situations, use feclearexcept() and fetestexcept():

Returns:

The complex hyperbolic sine of z.

If z is: These functions return:
+0+0i +0+0i
+0+i ±0+NaNi (the sign of the real part is unspecified) and FE_INVALID is raised
+0+NaNi ±0+NaNi
x+i (for any positive finite x) NaN+NaNi and FE_INVALID is raised
x+NaNi (for any positive finite x) NaN+NaNi and FE_INVALID may be raised
++0i ++0i
++yi (for any positive finite y) ++cis(y)
++i ±+NaNi (the sign of the real part is unspecified) and FE_INVALID is raised
++NaNi ±+NaNi (the sign of the real part is unspecified)
NaN+0i NaN+0i
NaN+yi (for any finite nonzero y) NaN+NaNi and FE_INVALID may be raised
NaN+NaNi NaN+NaNi

where cis(y) is cos(y) + i sin(y)
