bitwisejs

BitwiseJs

Is a CommonJs Es6 module to manipulate bits.

Abstract

Because numeric values are default coded as floating-point in 64-bit format IEEE-754 \Ö/, unexpected results can popup while bitwise operations.
In order to operate, Number(s), I mean the integer part is stored in a 52 bits matissa.
Max integer value is 2^53 and min -2^53, read stackoverflow.
To raise this kind of caveat, ArrayBuffer usage is highly recommended to isolate bytes state before processing.
This may be used to build state machine or other stuffs...bitwise based.

Requirements

Prod

• Nodejs.

Dev

• Mocha module.
• Bash bc command.

Dependencies

• None

Setup

npm i

Test

Js

To run Mocha test suite :

npm test

Integration

Sample to integrate beta release

npm i https://gogs.pier-infor.fr/pf.pier-infor.fr/bitwisejs/archive/1.0.0.tar.gz --save

Bash

Replacing 'numberValue' by the value of the number. Get a bin view :

echo "obase=2;'numberValue'" | bc

Get an hex view :

echo "obase=16;'numberValue'" | bc

Linter

npm run lint

Todo

• Improve test coverage (wip).
• Describe module integration (forthcoming).
  
• Improve tests on float values (forthcoming).
