As far as I know round will only round it to the closest integer, so... it's impossible to do this with just round.

However, consider this...

1. if you were to multiple the number by 100

i.e. 3.1435030 * 100 = 314.35030

2. then round it up

Math.round(314.35030), you will get 314

3. now, divide it back by 100

i.e. 314 / 100 = 3.14

4. there you go, your answer is 3.14 (rounded to the nearest 2 decimal places.

so, the function you are looking for is:

function myRound( number , places )

{

//heh, I forgot how to do the exponential, so don't laugh :)

var factor = 10;

for (var i = 0;i < places;i++) factor *= factor

return (Math.round(number * factor))/factor

}

to round it to 3 decimal places, call it as:

myNumber = myRound(number_to_round,3)
