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.
