This is a very basic Roman numeral converter. Larger numbers are represented in lowercase notation, which is not standard. The standard is, for example, V (5000) or X (10000). A bar over top of the numeral represents that it's 1000 times more... but since you can not type a character like that on a computer keyboard, we will represent them with their lowercase equivalents instead.
