The decimal numeral system (also called base-ten positional numeral system, and occasionally called denary) is the standard system for denoting integer and non-integer numbers. It has ten as its base.
| decimal | 110 | 210 | 310 | 410 | 510 | 610 | 710 | 810 | 910 | 1010 |
| hexadecimal (base 16) | 120 | 220 | 320 | 420 | 520 | 620 | 720 | 820 | 920 | a20 |
The vigesimal or base 20 numeral system is based on twenty (in the same way in which the decimal numeral system is based on ten).
