Thank you for creating such a helpful and useful site. The letter M with a dash above it represents 1 million, eg x , the dash means x by , just as L with a dash above it means 50, An interesting website, though it has a very conventional approach to Roman Numerals -- the Romans themselves were not quite as strict, nor were many who used them afterwards.

The four "C"s in a row threw the program because that is not conventional, but was done sometimes, and putting an "I" for one before and "L" for fifty would not usually be how one does "49" since it would normally be more the complex XLIX.

The rules are not hard and fast, but more conventional versus a little more unusual -- this one uses them as if they were hard and fast. Works though, for that purpose.

In the Roman numeral system, the basic "digits" are the letters I , V , X , L , C , D , and M which represent the same numbers regardless of their position.

Symbols are placed in order of value, starting with the largest values. When the higher numeral is placed before a lower numeral, the values of each Roman numeral are added. When smaller values precede larger values, the smaller values are subtracted from the larger values, and the result is added to the total. Do not repeat I , X , and C more than three times in a row.
