That's cool and all but you just know that besides causing mass confusion among people who just can't stand it on principle, some shit at Google is going to throw a tantrum over it and advocate the removal of language features if you do something like that. I wish I was joking.

There is also the practical matter that not all FPUs are created equal, and you can end up with (even more) inaccurate values this way. I know it doesn't matter much when your FPU is in a bad way, I'm just saying that for every reason to use the function call, there are two equally insignificant reasons not to. Honestly the only really good reason I can think of not to is inertia.
