Day 4 of my Rust journey.
While building the nth Fiboncci program, I came accross the same weirdness around calculating with floats. I went with using phi to compute the value, instead of doing the O(n) approach, and had to make everything an f64. It seems you can't call .sqrt() on an int? Why is that? And so after I added .0 to all my numbers, I had to add _f64 to 5.0, to be able to call .sqrt() on it. But, the compiler knows that 1.0 is a float?
Seems really odd to have to do all of this. Would appreciate any feedback on this, and help understanding a better way.
