Number list

This page lists decimal, binary, octal and hexadecimal numbers. In addition, the page lists numbers in several unusual systems: ternary (or trinary, base-3), quaternary (base-4), quinary (base-5), senary (base-6), dozenal (or duodecimal, base-12) and vicesimal (base-20) numbers.

Decimal (base-10), binary (base-2), octal (base-8) and hexadecimal (base-16) numbers are commonly used in computing. Other bases are far less common.
