Definition of Radix
The radix is equal to the number of digits used to form numerals in a given number system.
For example,
- Since the decimal number system makes numbers out of the ten digits \(\{0,1,2,3,4,5,6,7,8,9\}\), its radix is \(10\).
- Since the binary number system makes numbers out of the two digits \(\{0,1\}\), its radix is \(2\).
- Since the ternary number system makes numbers out of the ten digits \(\{0,1,2\}\), its radix is \(3\).
- The hexadecimal number system makes numerals out of sixteen digits, so its radix is \(16\).
The term, radix can also refer to the number that is raised to a power.
For example, the radix of \(9^5\) is \(9\).
