ctanh, ctanf—complex hyperbolic tangent #include <complex.h>
double complex ctanh(double complex z);
float complex ctanhf(float complex z);
Description
These functions compute the complex hyperbolic tangent of z.
ctanhf is identical to ctanh, except that it performs
its calculations on floats complex.
Returns
These functions return the complex hyperbolic tangent value.
Portability
ctanh and ctanhf are ISO C99
