    Readme

    numeric-array-integer

    JavaScript numeric array implemented using bitwise operations on an integer.

    This implementation allows for simple and efficient storage of fixed length arrays of small integers as an integer.

    NPM version CI

    Install:

    $ yarn add numeric-array-integer

    Usage:

    // Initialize new NumericArrayInteger with bits per number 4 (max number is 2^4-1, 15), total bit length 10
const integer = new NumericArrayInteger(4, 10);

// Set number at position
integer.setPos(0, 3);
integer.setPos(2, 2);

// Get data as an integer
const data = integer.getData();
console.log(data); // 515

// Load data from an integer
const integer2 = NumericArrayInteger.fromData(data, 4, 10);

// Get back original number at position
console.log(integer2.getPos(0)); // 3
console.log(integer2.getPos(2)); // 2
