2 frem - remove specified integer factors from specified integer
11 return non-negative integer
14 If x and y are not zero and n is the largest non-negative integer
15 for which y^n is a divisor of x, frem(x,y) returns abs(x/y^n).
16 In particular, abs(x) is returned if x is not divisible by
17 y or if abs(y) = 1. If abs(y) > 1, frem(x,y) is the greatest
18 divisor of x not divisible by y.
20 For all x, frem(x,0) is defined to equal abs(x).
22 For all y, frem(0,y) is defined to be zero.
24 For all x and y, abs(x) = frem(x,y) * abs(y) ^ fcnt(x,y).
