provides procedures for arithmetic operations on binary numbers in strings.

The bstrith provides procedures to handle binary integers written in strings. The primary purpose is to provide the functions for some operations, including arithmetic, bit, logical, and comparison operations.

• arithmetic operations
  • add
  • sub
• bit operations
  • shift
  • shift_l
  • shift_r
• logical operations
  • and
  • or
  • xor
  • not
• comparison operations
  • is_equal
  • is_not_equal

    use :: bstrith
    print *, add("11111111", "00000001") ! "00000000"
    print *, sub("00000000", "00000001") ! "11111111"

bstrith has been tested only on Windows 10 but may also work on Linux/MacOS. The compilers and versions listed below have been used to develop Strith.

• A Fortran 2008 compiler
  • gfortran 11.2 bundled with quickstart Fortran on Windows
  • Intel Fortran Classic 2021.5.0 Build 20211109_000000
  • NAG Fortran 7.1 Build 7117
• Fortran Package Manager (fpm) 0.9.0 alpha

To get the code, execute the following commnad:

git clone https://github.com/degawa/bstrith.git
cd strish

To build the library using fpm, execute the following command:

fpm build

Add the following use statement to modules or procedures calling bstrith.

use :: bstrith

To use Strith in your fpm project, add the following to the fpm.toml.
