catanf(3M)

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, +++++ππi ] 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 [ −π/2, +π/2 ] along the real axis.

Errors

No errors are defined.
