Div, Mod

Syntax

Div(N:INT,D:INT):INT
Mod(N:INT,D:INT):INT
    

Summary

quotient and remainder for integers

Description

If N = Q*D + R, and 0 <= R < |D|, then Div(N,D) returns Q and Mod(N,D) returns R.

NOTE: To perform the division algorithm on a polynomial or vector, use NR (normal remainder) to find the remainder, or DivAlg to get both the quotients and the remainder. To determine if a polynomial is in a given ideal or a vector is in a given module, use NF or IsIn, and to find a representation in terms of the generators use GenRepr.

example

    
Div(10,3);
