About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Binary String

Return a string giving the literal bit representation of an unsigned 32-bit integer.

Installation

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

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

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

toBinaryString( x )

Returns a string giving the literal bit representation of an unsigned 32-bit integer.

var Uint32Array = require( '@stdlib/array-uint32' );

var a = new Uint32Array( [ 1, 4, 9 ] );

var str = toBinaryString( a[0] );
// returns '00000000000000000000000000000001'

str = toBinaryString( a[1] );
// returns '00000000000000000000000000000100'

str = toBinaryString( a[2] );
// returns '00000000000000000000000000001001'

Notes

• Except for typed arrays, JavaScript does not provide native user support for unsigned 32-bit integers. According to the ECMAScript standard, number values correspond to double-precision floating-point numbers. While this function is intended for unsigned 32-bit integers, the function will accept floating-point values and represent the values as if they are unsigned 32-bit integers. Accordingly, care should be taken to ensure that only nonnegative integer values less than 4,294,967,296 (2^32) are provided.

  var str = toBinaryString( 1 );
  // returns '00000000000000000000000000000001'
  
  str = toBinaryString( 4 );
  // returns '00000000000000000000000000000100'
  
  str = toBinaryString( 9 );
  // returns '00000000000000000000000000001001'
  
  str = toBinaryString( 4294967295 );
  // returns '11111111111111111111111111111111'

Examples

var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var Uint32Array = require( '@stdlib/array-uint32' );
var toBinaryString = require( '@stdlib/number-uint32-base-to-binary-string' );

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

// Generate random unsigned 32-bit integers...
x = new Uint32Array( 100 );
for ( i = 0; i < x.length; i++ ) {
    x[ i ] = round( randu()*1.0e5 );
}

// Convert unsigned 32-bit integers to literal bit representations...
for ( i = 0; i < x.length; i++ ) {
    b = toBinaryString( x[i] );
    y = parseInt( b, 2 );
    console.log( 'x: %d, b: %s, y: %d', x[i], b, y );
}
