Composite, Odd, Fractions

[Kwing]

How do I ask Flash to check if a variable is composite or odd? How do I ask it to check if it's a whole number or a fraction/decimal?

I'm making a racing game, and it's going to have two checkpoints, each of which add 0.5 to the Lap. It's going to look something like this:

onClipEvent(enterFrame){
if(this.hitTest(_parent.player)||_parent.laps=_whole){
laps+=0.5;
}}

Except that I don't know how to check for whole or decimal/fractions.

I think you're over complicating things; what exactly do you want to do?

when a number is odd, its last bit must be 1.

You can use Modulus:

myVar % 2 ? trace("myVar is even") : trace("myVar is odd");

Same thing for decimal numbers:

myVar %1 ? trace("Not decimal") : trace("Is decimal");

BTW, "? : " is a fancy way of doing if(){}else{} ; :p
