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!
Test if two double-precision floating-point numbers are the same value.
import isSameValueZero from 'https://cdn.jsdelivr.net/gh/stdlib-js/number-float64-base-assert-is-same-value-zero@esm/index.mjs';Tests if two double-precision floating-point numbers a and b are the same value.
var bool = isSameValueZero( 3.14, 3.14 );
// returns true
bool = isSameValueZero( 5.0, 3.0 );
// returns falseIn contrast to the strict equality operator ===, the function treats NaNs as the same value.
var bool = ( NaN === NaN );
// returns false
bool = isSameValueZero( NaN, NaN );
// returns trueIn 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 = isSameValueZero( 0.0, -0.0 );
// returns true
