Although x and y's possible types include float32, there are two steps in
"var f float32 = x / y".
The first one is "x / y", for both default type of x and y is int, so the
result is 1.
The second step is "var f float32 = 1".
This is it.
If you change 5 to 5.0, or change 3 to 3.0,
then the first step will operate on two Float values, the intersection
possible types of 5.0 and 3 (or 5 and 3.0) are float types.
