Easy way to round numbers (28.563 to 28.56)?

[ryanc]

I was wondering if there was an easy way to round numbers, like rounding 28.5633453 to 28.56, or do I need to get a substring of the number (28.563), see if the last digit is greater than 5, then increment the hundredths place digit? Seems like there should be an easy way to do this...(in JavaScript)

You can use Math.round like so:

function roundMe(num,places){
num *= Math.pow(10,places);
num = Math.round(num);
num /= Math.pow(10,places);
return num;
}
