A letter with a bar over it multiplies that value by 1,000. For example, M equals 1,000,000. These numbers can be entered by putting an underscore before the letter, for example, _M will mean M.

*Technically*, 4 million or above cannot be represented in roman numerals, however I have added functionality for it.
