NAME
ctanh, ctanhf, ctanhl - complex hyperbolic tangent
LIBRARY
Math library (libm, -lm)
SYNOPSIS
bash
#include <complex.h>bash
double complex ctanh(double complex \nz\n);\n
\nfloat complex ctanhf(float complex \nz\n);\n
\nlong double complex ctanhl(long double complex \nz\n);DESCRIPTION
These functions calculate the complex hyperbolic tangent of z.
The complex hyperbolic tangent function is defined mathematically as:
bash
ctanh(z) = csinh(z) / ccosh(z)ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
