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