ctanh, ctanhf, ctanhl - complex hyperbolic tangent
double complex ctanh(double complex
float complex ctanhf(float complex
long double complex ctanhl(long double complex
These functions calculate the complex hyperbolic tangent of
The complex hyperbolic tangent function is defined mathematically as:
ctanh(z) = csinh(z) / ccosh(z)
These functions first appeared in glibc in version 2.1.
