csqrt, csqrtf, csqrtl - complex square root functions
double complex csqrt(double complex z);
float complex csqrtf(float complex z);
long double complex csqrtl(long double complex z);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.
These functions shall compute the complex square root of z, with a branch cut along the negative real axis.
These functions shall return the complex square root value, in the range of the right half-plane (including the imaginary axis).
No errors are defined.
