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!

isNegativeZero

Test if a value is a number equal to negative zero.

Installation

1npm install @stdlib/assert-is-negative-zero

Usage

1var isNegativeZero = require( '@stdlib/assert-is-negative-zero' );

isNegativeZero( value )

Tests if a value is a number having a value equal to negative zero.

1var Number = require( '@stdlib/number-ctor' );
2
3var bool = isNegativeZero( -0.0 );
4// returns true
5
6bool = isNegativeZero( new Number( -0.0 ) );
7// returns true
8
9bool = isNegativeZero( -3.14 );
10// returns false
11
12bool = isNegativeZero( 0.0 );
13// returns false
14
15bool = isNegativeZero( null );
16// returns false

isNegativeZero.isPrimitive( value )

Tests if a value is a primitive number equal to negative zero.

1var Number = require( '@stdlib/number-ctor' );
2
3var bool = isNegativeZero.isPrimitive( -0.0 );
4// returns true
5
6bool = isNegativeZero.isPrimitive( new Number( -0.0 ) );
7// returns false

isNegativeZero.isObject( value )

Tests if a value is a Number object having a value equal to negative zero.

1var Number = require( '@stdlib/number-ctor' );
2
3var bool = isNegativeZero.isObject( -0.0 );
4// returns false
5
6bool = isNegativeZero.isObject( new Number( -0.0 ) );
7// returns true

Examples

1var Number = require( '@stdlib/number-ctor' );
2var isNegativeZero = require( '@stdlib/assert-is-negative-zero' );
3
4var bool = isNegativeZero( -0.0 );
5// returns true
6
7bool = isNegativeZero( new Number( -0.0 ) );
8// returns true
9
10bool = isNegativeZero( -3.14 );
11// returns false
12
13bool = isNegativeZero( 0.0 );
14// returns false
15
16bool = isNegativeZero( 5.0 );
17// returns false
18
19bool = isNegativeZero( '-0' );
20// returns false
21
22bool = isNegativeZero( null );
23// returns false

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.
