fpview, a bitwise viewer of IEEE754 floating number on terminal

This tool shows colored, commented bitwise views of IEEE754 floating numbers, both single-precision and double-precison on terminal.

I wrote this as I recently need to deal with a lot of bitwise operation of floating numbers. And I hope this helps you out.

Usage

fpview (-s/--single) (-f/--float) (-d/--double) (-b/--both) (--) [number 1] ([number 2] (...))

• -h/--help print a help message
• -s/--single show only single-precision bitwise view
• -f/--float alis to -s/--single
• -d/--double show only double-precision bitwise view
• -b/--both show both single-precision and double-precision bitwise views (default)

Hint: due to the nature of argument parsing, you might want to add -- before all numbers

Examples

• To get bitwise views of single-precision fp numbers 1.0 and 2.0:

  fpview --single 1.0 2.0
  

• To get bitwise views of double-precision fp numbers -0.1 and -0.2:

  fpview --double -- 0.1 0.2
  

• To get bitwise views of both single-precision and double-precision fp numbers 1.234 -2.3441 5.61323 -10.2323:

  fpview -- 1.234 -2.3441 5.61323 -10.2323
  

Build

Make sure you have cmake installed, do build it, run the following commands this the current directory:

cmake -B build
cmake --build build

The result binary would be build/fpview
