ccos(), ccosf(), ccosl()

Compute the complex cosine

Synopsis:

#include <complex.h>

double complex ccos( double complex z );

float complex ccosf( float complex z );

long double complex ccosl( long double complex z );

Arguments:

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

Library:

libm

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

Description:

These functions compute the cosine of z. The cosine is an entire function on the complex plane, and has no branch cuts.

Returns:

The cosine of z. Errors and special cases are handled as if the operation were implemented as ccosh(i * z).
