How it works

Integer operands are converted to binary words and evaluated with bitwise AND, OR, XOR, and left or right shifts. The result is shown in decimal, binary, and hexadecimal so each changed bit can be inspected.

  • A 32-bit display is a familiar debugging view.
  • Large integer input is kept exact instead of passing through floating-point Number.

Worked example

Bitwise AND
Perform a bitwise AND on two values (masking)
Input
											255, 15
Output
												255 AND 15 = 15
Decimal: 15
Binary: 1111
Hex: 0xF
Octal: 0o17

When to use this

Feature flags, packed network headers, and systems programming exercises inspect bit masks.

Edge cases

  • Negative operands need a selected width for a finite two’s-complement display.
  • A shift beyond the displayed width can erase every bit or widen the integer.
  • Values above 2^53 lose Number precision, so large values are treated as BigInt text.
