Numbers have always fascinated me. And the different ways that humans represented numbers over the years, from the Egyptians to the Greeks to the Romans. So I wanted a quick way to convert between the numerals we currently use and the different ways numbers have been represented in the past. And as a programmer who also spent time converting numbers into binary, octal, and hexadecimal, I thought it would be good to include all the number bases from binary (Base 2) through Hexatrigesimal (Base 36).
