OK, you get me :))

Just for the fun of it:

any number X can be represented in form  X = p * q + r , (q would be 12
in this case), r-reminder so:

    EVAL    r = X - q * %int(X/q)

but my favorite is this beautiful algorithm that uses only subtraction
in order to calculate reminder:

r = X;
Do While r >= q
r = r - q;
End Do

What is left is r - reminder from X divided by q.


It can be modified to calculate result of division also:

r = X;
p = 0;
Do While r >= q
r = r - q;
p = p + 1;
End Do

r - reminder
p - result of the division X/q


Have fun,
