NAME

12       ctanh, ctanhf, ctanhl — complex hyperbolic tangent functions
13

SYNOPSIS

15       #include <complex.h>
16
17       double complex ctanh(double complex z);
18       float complex ctanhf(float complex z);
19       long double complex ctanhl(long double complex z);

DESCRIPTION

22       The functionality described on this reference page is aligned with  the
23       ISO C  standard.  Any  conflict between the requirements described here
24       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
25       defers to the ISO C standard.
26
27       These functions shall compute the complex hyperbolic tangent of z.
28

RETURN VALUE

30       These functions shall return the complex hyperbolic tangent value.
