Is 4.03 greater than 4.030

Well, honey, technically speaking, 4.03 is the same as 4.030 because those extra zeros at the end don't mean diddly squat when it comes to the value. So, in the grand scheme of things, they're both equal and trying to argue otherwise is like trying to argue that a hot dog is a sandwich. Just enjoy the numbers for what they are and move on with your day.
