The lexer decides which type of number a numeric value is.
So 123 is an integer and 123.0 is a real.

All operations on values of the same type give values of that type,
except that division always gives a real. There is a new integer
division operation, denoted by //.

So 13/4 gives 3.25 and 13//4 gives 3. Also, 12/4 gives 3.0 and 12//4 gives 3.

No. And it cannot be disabled either.
