Learn the four supported bases.
Binary / Base 2⌄
Binary uses only 0 and 1. It is the language of bits, storage and digital logic. Number System helps you convert binary into human-friendly decimal or compact hexadecimal formats.
Octal / Base 8⌄
Octal uses digits 0 to 7. It groups binary data into three-bit sets, which is useful in some computing and permission contexts.
Decimal / Base 10⌄
Decimal is the everyday number system. It is the easiest reference point when checking values from binary, octal or hexadecimal.
Hexadecimal / Base 16⌄
Hexadecimal uses 0–9 and A–F. It is common in RGB/ARGB colors, memory addresses, byte values and debugging output.
