Question

I randomly generate a decimal using:

private function randomNumber(min:Number, max:Number):Number
    {
        return Math.random() * (max - min) + min;
    }

It comes out with something like 1.34235346435.

How can I convert it so that its 1.3.

Answer 1

You can round to one decimal place like this;

var newValue:Number = Math.round(oldValue * 10)/10

Or an arbitrary number of decimal places like this:

function round2(num:Number, decimals:int):Number
{
    var m:int = Math.pow(10, decimals);
    return Math.round(num * m) / m;
}
trace(round2(1.3231321321, 3)); //1.323
