Exponentiation operator works funny for negative exponents #962

Closed asanzo closed 8 years ago

asanzo commented 8 years ago

Here an example:

5 * (-1) => 0 5.0 * (-1) => Invalid operation 5 \ (-1.0) => 0.2

seleccion_256

Shouldn't it work for the three cases just the same?

According to our latest talks about number coercion or even having only one type of numbers, these operations should be equivalent.

More "strict" (?) languages, make a difference between integer and real exponentiation, but I think we can easily forget about it, it adds complexity we do not need. (To be clear: even if we would keep the complexity there is a but there... or I am not capable of understanding the behavior.)
