# Definition of Quaternary

**Quaternary** numbers are made up only of the digits \(\{0,1,2,3\}\). Each place in a quaternary number corresponds to a power of \(4\).

Because there are only \(4\) different possible digits in a quaternary number, we also call them Base \(4\) numbers.

For example, the quaternary number \(1203\) is equal to the decimal number \(1 \times 4^3 + 2 \times 4^2 + 0 \times 4^1 + 3 \times 4^0 = 64 + 2 \times 16 + 0 + 3 = 99\).

Some other examples of quaternary numbers are:

- \(33\), which corresponds to the decimal number \(15\).
- \(300\), which corresponds to the decimal number \(48\).
- \(101\), which corresponds to the decimal number \(17\).
