NAME

       ctan, ctanf, ctanl - complex tangent function

SYNOPSIS

       #include <complex.h>

       double complex ctan(double complex z);
       float complex ctanf(float complex z);
       long double complex ctanl(long double complex z);

       Link with -lm.

DESCRIPTION

       These functions calculate the complex tangent of z.

       The complex tangent function is defined as:

           ctan(z) = csin(z) / ccos(z)

VERSIONS

       These functions first appeared in glibc in version 2.1.
