csqrtl3
Complex square root
Part of csqrt(3).
Usage
double complex
csqrt(double
complex
z);
float
complex
csqrtf(float
complex
z);
long
double
complex
csqrtl(long
double
complex
z);
Library
Math library (libm, -lm)
Overview
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.)
