csqrt, csqrtf, csqrtl - complex square root
double complex csqrt(double complex
float complex csqrtf(float complex
long double complex csqrtl(long double complex
These functions calculate the complex square root of
z, 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.)
These functions first appeared in glibc in version 2.1.
