Number systems

Hissab supports decimal, binary, octal, and hexadecimal literals.

Conversion

Targets are binary, octal, decimal, and hex.

0xff to binary
0o755 to hex
255 to octal

Use hex, not hexadecimal, as the conversion target.

Arithmetic across bases

You can mix bases freely and convert the final result.

0b10011010 + 0x1a to decimal
0xff & 0x0f to decimal

Notes

  • If you do not append to <base>, output formatting follows the left operand's base.
  • Negative numbers in non-decimal bases are not supported as literals. Compute with positive literals and negate the result separately if needed.

Common mistakes

  • 255 to hexadecimal is invalid — use 255 to hex.
  • Digits must fit the base — binary uses 0–1, octal uses 0–7, and hex uses 0–9 plus a–f.
