@stdlib/number-uint32-base-from-binary-string NPM

From Binary String

Create an unsigned 32-bit integer from a literal bit representation.

Installation

npm install @stdlib/number-uint32-base-from-binary-string

Usage

var fromBinaryStringUint32 = require( '@stdlib/number-uint32-base-from-binary-string' );

fromBinaryStringUint32( bstr )

Creates an unsigned 32-bit integer from a literal bit representation.

var bstr = '01010101010101010101010101010101';
var val = fromBinaryStringUint32( bstr );
// returns 1431655765

bstr = '00000000000000000000000000000000';
val = fromBinaryStringUint32( bstr );
// returns 0

bstr = '00000000000000000000000000000010';
val = fromBinaryStringUint32( bstr );
// returns 2

bstr = '11111111111111111111111111111111';
val = fromBinaryStringUint32( bstr );
// returns 4294967295

Examples

var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var MAX_UINT = require( '@stdlib/constants-uint32-max' );
var toBinaryStringUint32 = require( '@stdlib/number-uint32-base-to-binary-string' );
var fromBinaryStringUint32 = require( '@stdlib/number-uint32-base-from-binary-string' );

var b;
var x;
var y;
var i;

// Convert random integers to literal bit representations and then convert them back...
for ( i = 0; i < 100; i++ ) {
    x = round( randu()*MAX_UINT );
    b = toBinaryStringUint32( x );
    y = fromBinaryStringUint32( b );
    console.log( '%d => %s => %d', x, b, y );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
