multiply integer to float

I think it would be convenient to allow multiplying float with integers to get back an float.

let a = 32.0;
let b = 2;

dbg!(a*b);

Is there a particular reason I need to use 2.0 to get the result I want?

This is currently intentional and changing it is probably fundamental enough to warrant going through the RFC process, so closing in favor of that.
