6 ctanh, ctanhf \- complex hyperbolic tangent functions
9 \fB#include <complex.h>
12 double complex ctanh(double complex\fP \fIz\fP\fB);
14 float complex ctanhf(float complex\fP \fIz\fP\fB);
19 These functions compute the complex hyperbolic tangent of \fIz\fP.
22 These functions return the complex hyperbolic tangent value.
