Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Readme
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!
Test if two single-precision floating-point numbers are the same value.
npm install @stdlib/number-float32-base-assert-is-same-value-zero
var isSameValueZerof = require( '@stdlib/number-float32-base-assert-is-same-value-zero' );
Tests if two single-precision floating-point numbers a
and b
are the same value.
var toFloat32 = require( '@stdlib/number-float64-base-to-float32' );
var bool = isSameValueZerof( toFloat32( 3.14 ), toFloat32( 3.14 ) );
// returns true
bool = isSameValueZerof( toFloat32( 5.0 ), toFloat32( 3.0 ) );
// returns false
In contrast to the strict equality operator ===
, the function treats NaNs
as the same value.
var bool = ( NaN === NaN );
// returns false
bool = isSameValueZerof( NaN, NaN );
// returns true
In contrast to the SameValue Algorithm (as specified in ECMAScript 5), the function does not distinguish between +0
and -0
.
var bool = ( 0.0 === -0.0 );
// returns true
bool = isSameValueZerof( 0.0, -0.0 );
// returns true
bool = isSameValueZerof( -0.0, 0.0 );
// returns true
var toFloat32 = require( '@stdlib/number-float64-base-to-float32' );
var isSameValueZerof = require( '@stdlib/number-float32-base-assert-is-same-value-zero' );
var bool = isSameValueZerof( toFloat32( 3.14 ), toFloat32( 3.14 ) );
// returns true
bool = isSameValueZerof( toFloat32( 0.0 ), toFloat32( 0.0 ) );
// returns true
bool = isSameValueZerof( toFloat32( -0.0 ), toFloat32( 0.0 ) );
// returns true
bool = isSameValueZerof( toFloat32( NaN ), toFloat32( NaN ) );
// returns true
