NAME

13       ctan, ctanf, ctanl — complex tangent functions
14

SYNOPSIS

16       #include <complex.h>
17
18       double complex ctan(double complex z);
19       float complex ctanf(float complex z);
20       long double complex ctanl(long double complex z);

DESCRIPTION

23       The functionality described on this reference page is aligned with  the
24       ISO C  standard.  Any  conflict between the requirements described here
25       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
26       defers to the ISO C standard.
27
28       These functions shall compute the complex tangent of z.
