Number Converter
Bin / Dec / Hex / Oct; two's complement for negative inputs
About this tool
Number converter converts signed integers between binary, octal, decimal and hexadecimal without losing integer precision.
How to use
- Select the input base and enter an integer. Conversion updates immediately.
- For a negative input, the additional two’s-complement output shows the bit pattern modulo 2 to the selected bit width.
- A positive value that exceeds the selected width produces a warning; the ordinary base conversions retain the full value.
- Long output fields scroll horizontally and can be selected and copied.
