It's correct, that standard c does not have built in fixed point types. But that does not change the overall problem. When you write a constant in decimal notation you cannot be sure the corresponding computer representation is precise. This is the reason why you should never compare floats with an equals sign.

I agree with you though that the speed reasons becomes less important nower days. The question is if and when to switch for compatibility reasons.


"quants" is just a word. You can also define that 1 unit (i.e. quant) represents 1 meter or 1 centimeter in your game and you're good to go. If you're in a funny mood you can call those quants also "ventilator", or "schokoflocken". This has nothing to do with the data type. It's just a name for the units.


Unfortunately. I'd be the first to sign a petition to make it 100% compatible at this very moment. Adding even more exceptions to the number of incompatibilities is at least from my point of view not the way to go.
