NAME

catan, catanf, catanl - complex arc tangent functions

SYNOPSIS

c99 [ flag… ] file-lm [ library… ]
#include <complex.h>

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, +++++pipii ] 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 [ −pi/2, +pi/2 ] along the real axis.

ERRORS

No errors are defined.
