Computes complex square roots.
#include <complex.h>
double complex csqrt (z)
double complex z;
float complex csqrtf (z)
float complex z;
long double complex csqrtl (z)
long double complex z;
The csqrt, csqrtf, and csqrtl subroutines compute the complex square root of the value specified by the z parameter, with a branch cut along the negative real axis.

z | Specifies the value to be computed. |
The csqrt, csqrtf, and csqrtl subroutines return the complex square root value, in the range of the right half-plane (including the imaginary axis).
