NAME
       csqrt, csqrtf, csqrtl - complex square root functions

SYNOPSIS
       #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  shall  compute the complex square root of z, with a branch cut along the
       negative real axis.

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