[issue39788] Exponential notation should return an int if it can

Sorry, but I can't figure out what code can break this change. Integers are implicitly converted to floats in operations with floats. How can this change break old code?

No, I'm worried about the expectations of coders.
Personally, I expected that 1E2 returned a integer. And this is not true.
If I wanted a float, I'd wrote 1.0E2 . The fact the exponential notation returns always a float is really misleading, IMHO.
