NAME

csqrt, csqrtf, csqrtl - complex square root functions

SYNOPSIS

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

double complex csqrt(double complex z);


float complex csqrtf(float complex z);


long double complex csqrtl(long double complex z);

DESCRIPTION

These functions compute the complex square root of z, with a branch
cut along the negative real axis.

RETURN VALUES

These functions return the complex square root value, in the range of
the right half-plane (including the imaginary axis).

ERRORS

No errors are defined.
