Question

What’s the simplest way in actionscript to find if number is between -20 and +20, and return a true/false? I can see there’s a number validator but I see it involves firing and catching events, which I think maybe overkill for the simple test I’m trying to do here.

Answer 1

Simplest way would be comparing the number with both values and logical combine the results:

return num > -20 && num < 20;

You may use >= or <= to include the values if needed.

You can make that into a nice function:

function isBetween(num:Number, lowerBound:Number, upperBound:Number):Boolean {
    return num > lowerBound && num < upperBound;
}
