Some environments only expose float as the number type, love2d being one I know. Fortunately love is built on LuaJIT, which does support integer math through the built-in ‘ffi’ library.

My multiplayer arena game rounds reasonably-sized floats and compares them in the presentation layer, but uses fixed point integer math in the core rollback simulation

(I believe JS is a similar story, its number can be either int or float with no way to guarantee integer-only math. I never needed to consider the difference outside of currency for webdev, so I’m less sure)
