Calculate expression

$ bitwise "0x123 + 0x20 - 30"

SYNOPSIS

bitwise [OPTIONS] [value|expression]

DESCRIPTION

bitwise is a multi-base interactive calculator supporting dynamic base conversion and bit manipulation. It displays values in decimal, hexadecimal, octal, and binary simultaneously.

PARAMETERS

-i, --interactive

Force interactive mode (the default when no value or expression is given)

-w, --width b8|b16|b32|b64

Set the bit width of the calculation

--no-color

Disable colored output

-v, --version

Print version information

-h, --help

Show help message

Values can be specified in different bases:

Decimal: plain numbers (123)

Hexadecimal: 0x prefix (0x7B)

Octal: 0 prefix (0173)

Binary: 0b prefix (0b1111011)

Supports C-style arithmetic and bitwise operators (NOT, OR, AND, XOR, and shifts). In command-line mode the result is printed in all bases at once.

INSTALL

sudo apt install bitwise

sudo dnf install bitwise

sudo apk add bitwise

sudo zypper install bitwise

brew install bitwise

nix profile install nixpkgs#bitwise

CAVEATS

Interactive mode provides a visual bit toggle interface. Expressions with special shell characters need quoting. Useful for low-level programming and debugging.

bitwise is an open-source (GPL-3.0) ncurses-based calculator written by Ramon Fried (mellowcandle). It targets low-level developers such as kernel and device-driver programmers who frequently work across number bases.
