Synopsis
#include <flint/fft_small.h>void fft_small_ifft(fft_small_op_t X, const fft_small_plan_t P)sourceApplies the inverse transform in place to an operand in the product domain, at the truncation of the plan. The normalisation was applied by the pointwise products. The primes are processed in parallel from P->ztrunc \ge 3072.
