Implementation status: to be implemented
double complex csqrt(double complex z);
float complex csqrtf(float complex z);
long double complex csqrtl(long double complex z);
The functions compute the complex square root of z, with a branch cut along the negative real axis.
z - a complex number.
These functions return the complex square root value, in the range of the right half-plane (including the imaginary axis).
No errors are defined.
