`nfloat_pow`

Synopsis#include <flint/nfloat.h>

int nfloat_pow(nfloat_ptr res, nfloat_srcptr x, nfloat_srcptr y, gr_ctx_t ctx)source

Sets res to $x^y = \exp(y \log|x|)$ , with the sign $(-1)^y$ for $x < 0$ and integer $y$ (NaN for $x < 0$ and noninteger $y$ ). Simple cases ( $y = \pm 1, 2, \pm 1/2$ , $|x| = 1$ , integer powers of powers of two) are handled directly.
