NAME

6       ctanh, ctanhf, ctanhl - complex hyperbolic tangent
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex ctanh(double complex z);
12       float complex ctanhf(float complex z);

DESCRIPTION

18       These functions calculate the complex hyperbolic tangent of z.
19
20       The complex hyperbolic tangent function is defined mathematically as:
21
22           ctanh(z) = csinh(z) / ccosh(z)
23

VERSIONS

25       These functions first appeared in glibc in version 2.1.
