math.round(); question

[puresin]

hello,

is it possible to round a floating point number to a certain
value?

what i mean is:

i want to round 1.85038723 to 1.8504

(skip the last 4 numbers).

is there a possibility?

thx

here you go:

Math.roundDec = function (num,decPlaces) { 
var p = Math.pow(10,decPlaces);
return Math.round(num*p)/p;
}
