NAME
       csqrt, csqrtf, csqrtl - complex square root

SYNOPSIS
       #include <complex.h>

       double complex csqrt(double complex z);
       float complex csqrtf(float complex z);
       long double complex csqrtl(long double complex z);

       Link with -lm.

DESCRIPTION
       Calculate  the square root of a given complex number, with nonnegative real part, and with
       a branch cut along the negative real axis.  (That means that csqrt(-1+eps*I) will be close
       to I while csqrt(-1-eps*I) will be close to -I, if eps is a small positive real number.)

VERSIONS
       These functions first appeared in glibc in version 2.1.

CONFORMING TO
       C99.
