Rounding Values up to 2Decimal Places?

[Owenbooty]

If flash outputs the value

176.776695296637

in a trace, Math.round() makes it 177

how can i round it up to 2 Decimal Places?

176.78

num = Math.PI; trace(num);
// 3.14159265358979

value0= Math.round(num);  
trace(value0);   // 0 decimal place - result 3

value1= Math.round((num)*10)/10;  
trace(value1);   // 1 decimal place - result 3.1

value2= Math.round((num)*100)/100;  
trace(value2);   // 2 decimal place - result 3.14

value4= Math.round((num)*10000)/10000;  
trace(value4);   // 4 decimal place - result 3.1416

and using dog's tehcnique, you can make it into a function....for convenience

trace(roundNumber(1.22567890, 5)); //will return the value to 5 decimal places


function roundNumber(num:Number, noPlaces:Number):Number {
	return Math.round(num * Math.pow(10, noPlaces))/Math.pow(10, noPlaces);
}
