WebHow to calculate ab mod n. There are several ways to compute abmodn a b mod n. The most efficient method consists of: divide the exponent b b into powers of 2 by writing it in binary, obtaining b= (dk−1,dk−2,...,d1,d0 b = ( d k − 1, d k − 2,..., d 1, d 0 ). build the following table: (b)2 c0 = 1 dk−1 c1 ≡ c2 0 ⋅adk−1modn dk−2 ... WebDec 7, 2011 · This calculator does not have any modulo function. However there is quite simple way how to compute modulo using display mode ab/c (instead of traditional d/c ). How to switch display mode to ab/c: Go to settings ( Shift + Mode ). Press arrow down (to view more settings). Select ab/c (number 1).
