double complex catanh(double complex z);

float complex catanhf(float complex z);

long double complex catanhl(long double complex z);

Description

These functions compute the complex arc hyperbolic tangent of z, with branch cuts outside the interval [ -1, +1 ] along the real axis.

Return Values

These functions return the complex arc hyperbolic tangent value, in the range of a strip mathematically unbounded along the real axis and in the interval [ -iπ/2, +iπ/2 ] along the imaginary axis.

Errors

No errors are defined.
