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 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.
