Roman Numerals to Number

Roman Numerals to Number Conversion


Converting Roman numerals to numbers involves translating a Roman numeral representation back into its numeric value. Here's a basic guide for converting Roman numerals to numbers:

  • Start from the leftmost symbol of the Roman numeral.
  • Compare the value of the current symbol with the value of the next symbol to its right:
    • If the value of the current symbol is greater than or equal to the value of the next symbol, add the value of the current symbol to the total.
    • If the value of the current symbol is smaller than the value of the next symbol, subtract the value of the current symbol from the total.
  • Move to the next symbol and repeat the process until you've processed all the symbols.
  • The total value obtained from adding or subtracting the values of the symbols is the numeric value of the Roman numeral.

Here are some examples:

  • "IV" translates to 4 (5 - 1).
  • "IX" translates to 9 (10 - 1).
  • "XLIX" translates to 49 (50 - 10 + 1 - 10).
  • "CVI" translates to 106 (100 + 5 + 1).
  • "MMMCMXCIX" translates to 3999 (1000 + 1000 + 1000 - 100 + 100 - 10 + 10 - 1 + 10).

Remember that in Roman numerals, there are specific rules and conventions to be aware of, such as the subtraction rule (as described in the previous response) and the limit on repeating characters more than three times.
