The floating point's accuracy can be scaled to any value range, which is not possible for integers. I remember issues with Lightwave waaay back in the past where you got into trouble if you wanted to add very tiny detail to normally scaled object. Due to the object not utilising the whole integer range, you actually lost precision since you left part of the existing value range "unused". Floating point values in comparison can easily adept the object's proportions.

Just a quick 80's Maths question, what's the difference between
floating point
1.23456
and
Integer
123456
from an accuracy point of view?
Not a trick question, just trying to get my head around this.

If you were doing your maths back in the 70s you're nearly as old as I am
and probably didn't touch on digital maths.


Basically:

floating point; 1.2345, 53.676889. Integer, 1, 6, 2345 ....

Floating point slow, integer fast.
