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.

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.
