= Barrett reduction
{wiki=Barrett_reduction}
Barrett reduction is an algorithm used in the field of modular arithmetic, particularly for efficiently reducing large integers modulo a smaller integer. It is especially useful in cryptography and in computations involving large numbers where performance is critical. The Barrett reduction method is designed to avoid the expensive division operation typically associated with modular reduction. Instead of performing a direct division, it leverages precomputed values to carry out the reduction more efficiently. \#\#\# Basic Steps of Barrett Reduction 1.
