NAME
|
|
frem - remove specified integer factors from specified integer
|
|
|
|
SYNOPSIS
|
|
frem(x,y)
|
|
|
|
TYPES
|
|
x integer
|
|
y integer
|
|
|
|
return non-negative integer
|
|
|

DESCRIPTION
|
|
If x and y are not zero and n is the largest non-negative integer
|
|
for which y^n is a divisor of x, frem(x,y) returns abs(x/y^n).
|
|
In particular, abs(x) is returned if x is not divisible by
|
|
y or if abs(y) = 1. If abs(y) > 1, frem(x,y) is the greatest
|
|
divisor of x not divisible by y.
|
|
|
|
For all x, frem(x,0) is defined to equal abs(x).
|
|
|
|
For all y, frem(0,y) is defined to be zero.
|
|
|
|
For all x and y, abs(x) = frem(x,y) * abs(y) ^ fcnt(x,y).
