ctanh(3) | Library Functions Manual | ctanh(3) |
NAME¶
ctanh, ctanhf, ctanhl - complex hyperbolic tangent
LIBRARY¶
Math library (libm, -lm)
SYNOPSIS¶
#include <complex.h>
double complex ctanh(double complex z); float complex ctanhf(float complex z); long double complex ctanhl(long double complex z);
DESCRIPTION¶
These functions calculate the complex hyperbolic tangent of z.
The complex hyperbolic tangent function is defined mathematically as:
ctanh(z) = csinh(z) / ccosh(z)
