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.
