Most CPUs do just fine on floating point too.

I'm still getting used to that.

Floating point arithmetic _is_ integer arithmetic on the cpu level because of how floating point numbers work.

That's a good point - floating point operations are implemented with integer-math circuits (or at least can be - I'm not privy to how modern chip manufacturers implement them). E.g: your ALU may have an 11-bit adder specifically to add your f64 exponents.
