In general, you should probably only need integers to do UI code. The major exception is working with graphics APIs. But a lot of the work that the CPU will do revolves around coordinates which are always discrete.
Our internal vectors and rectangles should primarily be i32/u32 variants (or u16???), only converting to float when it's truly necessary for some final drawing operation (probably involving vertices etc.)
