Radix
Updated: 07/12/2017 by Computer Hope
Radix is the number of digits utilized in a positional number system before "rolling over" to the next digit's place. For example, in the base 10 number system, there is a total of 10 digits used (zero through nine), therefore, its radix is 10. In the base 2 number system, there are two numbers used (zero and one), so its radix is two. Other words that are synonymous with radix are base and root, in an arithmetic sense.
