NAME

6       csqrt, csqrtf, csqrtl - complex square root functions
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex csqrt(double complex z);
12       float complex csqrtf(float complex z);

DESCRIPTION

17       These  functions  shall  compute  the  complex square root of z, with a
18       branch cut along the negative real axis.
19

RETURN VALUE

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