When I do something like (-1) % 20, I expect the result to be 19, but i’m getting -1 instead. Is there another syntax I should be using to get modular arithmetic that restricts the range to positive numbers less than the thing I’m dividing by?

You can do negative mods with fposmod(-1, 20)
And cast it back to integer if you like, since it returns a float.
thanks for the suggestion! i ended up writing my own mod function because i’m not sure i can trust the rounding on floats

Way better function for this purpose is posmod.
You know, if a function has f in it, for float, it most likely has an int counterpart.
