UN Converter: Change numeral systems

The third part of the UN Converter can convert numbers writen in one numeral system into another (e.g. from binary into hexadecimal or Roman numeral system). If the input value is not a integer number, the number will be rounded down to the previous whole value. Conversions are done in real time as you type in your values.

Numbering systems are used to show different representations of numeric values. Each numbering system consists of characters that represent numeric digits. The binary, or base-2, numbering system is based on the same principles as the decimal, or base-10, numbering system. The only difference between the two numbering systems is that binary uses only two digits, 0 and 1, and the decimal numbering system uses 10 digits, 0 through 9. For base 16, you will need sixteen digits, and there are only ten numerals. So we use the letters A, B, C, D, E, F. These represent the decimal numbers 10, 11, 12, 13, 14 and 15.

Roman numerals
