Notes
Some browsers will not display all the Roman numeral characters correctly.
The letters I V X L C D M are often used because they look similar to the Roman characters.
Take care when using lower case (i v x l c d m) because the capital i can be confused with lower case L.
The symbols ↁ ↂ ↇ ↈ are rarley seen because it was unusual for the Romans to use large numbers
Most modern keyboards do not have any letters similar to ↁ ↂ ↇ ↈ
It is prudent to avoid mixing Roman Numerals with either Decimal or Negative numbers.
There is no symbol for 0 (zero) in the original Roman Numeral system.
