as true and false are 1 and 0. Null should be -1

[Antikore]

Usign -1 to detect when something returns null I think can be very useful. I suggested something before to use it.

Null should be like -1, as true can be 1 and false 0.
Example of use

Code: [Select]

if key = null //If no key is pressed
{
}

I suggested this. Only I suggested Key = none.
