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).
EXAMPLE
; print frem(7,4), frem(24,4), frem(48,4), frem(-48,4)
