Understanding Radix & Number Systems

A number system base (or radix) dictates how many distinct digit characters represent amounts. Decimal uses ten numbers (0-9). Binary uses two symbols (0 and 1). Hexadecimal uses sixteen characters (0-9 and A-F).

Character Range Checking

When dealing with developer calculations, inserting invalid base characters (e.g. entering the letter `F` inside a Binary input) triggers calculation exceptions. This tool validates inputs on-the-fly, instantly letting you know if a character violates the selected radix boundaries.
