How can I do mod without a mod operator?

Question

This scripting language doesn't have a % or Mod(). I do have a Fix() that chops off the decimal part of a number. I only need positive results, so don't get too robust.

Answer 1

Will

// mod = a % b

c = Fix(a / b)
mod = a - b * c

do? I'm assuming you can at least divide here. All bets are off on negative numbers.

Answer 2

a mod n = a - (n * Fix(a/n))

Answer 3

For posterity, BrightScript now has a modulo operator, it looks like this:

c = a mod b
