ANSI_SYNOPSIS
#include <complex.h>
double complex ctan(double complex <[z]>);
float complex ctanf(float complex <[z]>);
DESCRIPTION
These functions compute the complex tangent of <[z]>.
<<ctanf>> is identical to <<ctan>>, except that it performs
its calculations on <<floats complex>>.
RETURNS
These functions return the complex tangent value.
PORTABILITY
<<ctan>> and <<ctanf>> are ISO C99
