I have a game where money is used, but I divide other variables to find out how much an item is worth. So naturally I used Math.floor to round it to a whole number. But that's not helpful when you want to deal with penies (just not 10th's of a penny and etc). Is there anyway to round to 2 decimal places?
some people get them, some people don't;

Math.round(x * 100) / 100
By multiplying by 100 you're only rounding the digits past the 2nd decimal place. Then by dividing by 100 you're putting the decimal place back in the right position.
