Indeed, the assumption of Theorem 1 says that c' = c/2^{N+L} is a good approximation of 1/d. Then if n = qd + r, the fractional part of c'n is close to r/d, and multiplying by d reveals r. midnight horrors wiki black sunWebFaster Remainder by Direct Computation Applications to Compilers and Software Libraries DanielLemire*1 OwenKaser2 NathanKurz3 … midnight horrors wiki sponge furnace
