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
.
