# Number [![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] > [Constructor][mdn-number] which wraps a numeric value in an object.

## Installation ```bash npm install @stdlib/number-ctor ```

## Usage ```javascript var Number = require( '@stdlib/number-ctor' ); ``` #### Number( value ) Returns a [`Number`][mdn-number] object. ```javascript var v = new Number( 5.0 ); // returns ```

## Notes - This constructor should be used sparingly. **Always** prefer number primitives.

## Examples ```javascript var randu = require( '@stdlib/random-base-randu' ); var Number = require( '@stdlib/number-ctor' ); var v; var i; for ( i = 0; i < 100; i++ ) { v = new Number( randu() ); console.log( 'typeof %d: %s', v, typeof v ); } ```
