NumCon allows you to convert numbers into different bases. Simply enter a number and the application will show you the corresponding number in the new base when that button is pressed.

Supported bases are:

- Decimal (Base 10);
- Binary (Base 2);
- Octal (Base 8); and
- Hexadecimal (Base 16).

Note that NumCon will only allow you to enter valid digits for the selected base. For example, while entering binary only "1" and "0" will be enabled on the numeric keypad.

Version 3.1 allows a maximum value of 268,435,455 (decimal) to be entered and converted. If we receive feedback that this is too low then the limit will be increased.
