Daily Godot Tip #18: If you are using floats but want to make sure value checks aren't messed up by floating-point precision, godot has a built in is_equal_approx(float, float) function (programming.dev)

This is usable in any script. It checks to see if the two values differ by a very small value

Alt text: Code that says print(is_equal_approx(1, 0.99999999999)) and then the console log which has printed out true.

I'm guessing that if someone needs to define tolerance on such a small scale, they probably weren't going to depend on an "approximately equal" function in the first place.

Then again, if someone has been dealing with these sorts of comparisons for a while, they'd have their own way of achieving this, so I guess it can be a handy tool for people who are just getting into game development.
