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, wellwritten, studied, documented, tested, measured, and highquality 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!
Square Root
Compute an integer square root.
Installation
npm install @stdlib/mathbasespecialfastuint32sqrt
Usage
var sqrtUint32 = require( '@stdlib/mathbasespecialfastuint32sqrt' );
sqrtUint32( x )
Returns an approximate square root of an unsigned 32bit integer x
.
var v = sqrtUint32( 9 >>> 0 );
// returns 3
v = sqrtUint32( 2 >>> 0 );
// returns 1
v = sqrtUint32( 3 >>> 0 );
// returns 1
v = sqrtUint32( 0 >>> 0 );
// returns 0
Notes
 Prefer hardware
sqrt
over a software implementation.  When using a software
sqrt
, this implementation provides a performance boost when an application requires only approximate computations for integer arguments.  For applications requiring highprecision, this implementation is never suitable.
Examples
var sqrtUint32 = require( '@stdlib/mathbasespecialfastuint32sqrt' );
var v;
var i;
for ( i = 0; i < 101; i++ ) {
v = sqrtUint32( i >>> 0 );
console.log( 'sqrt(%d) ≈ %d', i, v );
}

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.
