double complex catan(double complex z);

float complex catanf(float complex z);

long double complex catanl(long double complex z);

Description

These functions compute the complex arc tangent of z, with branch cuts outside the interval [ −i, +++++????i ] along the imaginary axis.

Return Values

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

Errors

No errors are defined.
