An integer conversion utility.

Intspector is a command line utility for converting integers between bases. It accepts an integer in binary, octal, decimal, or hex form, then prints it out in all four bases.


Run intspector --help to view the command line help.

Usage: intspector [integers]

  Integer conversion utility. Accepts integer input in [b]inary,
  [o]ctal, [d]ecimal, or he[x]adecimal base, then displays the
  number in all four bases.

  Use a single letter prefix to declare the base of the input,
  e.g. b1010. The base defaults to decimal if no prefix is

  This utility:

  - Accepts integer literals with a leading zero, e.g. 0x123.
  - Accepts multiple arguments.
  - Accepts input in the signed 64-bit integer range.
  - Displays the two's complement value for negative integers.

  [integers]            List of integers to convert.

  -b, --bits <n>        Number of binary digits to display.
                        (Determines the two's complement value
                        for negative integers.)

  -h, --help            Print this help text.
  -v, --version         Print the application's version number.

  cp2l, codepoint-to-literal    Convert unicode codepoints to
                                character literals.
  l2cp, literal-to-codepoint    Convert character literals to
                                unicode code points.

Command Help:
  help <command>        Print the specified command's help text.
