While near to zero, the differences prevent reliable equality testing and differences can accumulate. For this reason, decimal is preferred in accounting applications which have strict equality invariants.

WebJan 12, 2024 · An integer (fixpoint) can display all values within it's range, while float only covers 0%. Now, I'm not endorsing that view as the whole truth. For example, fixed point requires all code plus input data a given program to agree on the required dynamic range, Which would be very easy to do for a game, as it has to be done only within the game.
