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.
