ctan(), ctanf(), ctanl()

Compute the complex tangent

Synopsis:

#include <complex.h>

double complex ctan( double complex z );

float complex ctanf( float complex z );

long double complex ctanl( long double complex z );

Arguments:

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

Library:

libm

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

Description:

These functions compute the complex tangent of z.

Returns:

The complex tangent of z. Errors and special cases are handled as if the operation were implemented as -i * ctanh(i * z).
