BaseConverter

Converts an attribute's value from one numeric system (base) to another, putting the resulting value in a new attribute. The base is the number of unique digits, including zero, that a positional numeral system uses to represent numbers.

The most common base values are 2 (binary), 10 (decimal) and 16 (hexadecimal), and 8 (octal). The BaseConverter supports bases from 2 (binary) to 36 (hexatridecimal / sexatrigesimal).
