Base Convert - A library for easy conversion between numerical systems
Base Convert is an extensible JavaScript library to enable easy conversion between numerical systems, such as different bases (binary, decimal, hexadecimal) or roman numerals.
Goal: be able to convert numbers from and into all the world's different numerical systems.
Examples
Base(10, 2, "5.3") // 101.0100110...
Base(10, "roman", "2598") // MMDXCVIII
Base(2, 13, "110110") // 42
