Actionscript:
-
var someValue:Number = 2.0480531167374427;
-
-
// want to show only 3 decimal places?
-
trace(someValue.toFixed(3)); // outputs 2.048
An easy way to get rid of extra decimal values. This is useful when you want to show decimal values in text fields. I only recently noticed this in the docs, I used to do this type of thing:
Actionscript:
-
trace(int(someValue * 1000) / 1000); // outputs 2.048
