trig_prod_t
Synopsis
#include <flint/arith.h>trig_prod_tA product of cosines of rational multiples of \pi times an algebraic prefactor, \mathit{prefactor} \cdot \sqrt{\mathit{sqrt\_p} / \mathit{sqrt\_q}} \cdot \prod_{i < \mathit{n}} \cos(\pi\, \mathit{cos\_p}[i] / \mathit{cos\_q}[i]), with the fields named as in the formula (at most FLINT_BITS factors). An array of length one of trig_prod_struct.
