WebThe algorithm follows a split, evaluate (forward FFT), pointwise multiply, interpolate (inverse FFT), and combine phases similar to Karatsuba and Toom-Cook methods. Given input numbers x and y, and an integer N, the following algorithm computes the product xy mod 2 N + 1. Provided N is sufficiently large this is simply the product.
