Binary to Roman Converter



Converting a Binary Number to Roman Numerals

The binary numeral system (base-2) uses only two digits: 0 and 1. It is the foundation of all binary code and digital systems. Roman numerals are an ancient numeral system that uses combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M, each representing specific values. To convert a binary number to Roman numerals, we first convert the binary number to its decimal (base-10) equivalent and then convert that decimal number to Roman numerals.

For example, the binary number 11011100 can be converted to decimal as follows:

1 × 2^7 + 1 × 2^6 + 0 × 2^5 + 1 × 2^4 + 1 × 2^3 + 1 × 2^2 + 0 × 2^1 + 0 × 2^0

The sum is:

128 + 64 + 16 + 8 + 4 = 220

The decimal number 220 is then converted to Roman numerals, which is CCXX.
