CSQRT(3M) Mathematical Library Functions CSQRT(3M)

csqrt, csqrtf, csqrtl - complex square root functions

#include <complex.h>
double complex csqrt(double complex z);

float complex csqrtf(float complex z);

long double complex csqrtl(long double complex z);

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

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

No errors are defined.
