How would I get a relative point between a min and max value that could be represented as a float between 0.0 and 1.0? (lemmy.world)

I have a min and max position of an object and I want to represent an arbitrary point between them as a float between 0.0 and 1.0. This feels relatively basic math, but I can't quite figure out what I need to do with this. Is there a special name for this sort of thing? Also, are there any built-in methods that would be useful for this?

Related, note that division is much slower than multiplication.

Instead of:

n / d

see if you can refactor it to:

n * (1.0/d)

where that inverse can then be hoisted out of loops.
