stdlib-jsWe 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!
reviveBasePRNG
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
Revive a JSON-serialized pseudorandom number generator (PRNG).
bash
npm install @stdlib/random-base-reviver
javascript
var reviveBasePRNG = require( '@stdlib/random-base-reviver' );
#### reviveBasePRNG( key, value )
Revives a JSON-serialized pseudorandom number generator (PRNG).
javascript
var parseJSON = require( '@stdlib/utils-parse-json' );
var randu = require( '@stdlib/random-base-randu' );
var str = JSON.stringify( randu );
var rand = parseJSON( str, reviveBasePRNG );
// returns <Function>
For details on the JSON serialization format, see the .toJSON() method for, e.g., [randu()][@stdlib/random/base/randu].
javascript
var randu = require( '@stdlib/random-base-randu' );
var parseJSON = require( '@stdlib/utils-parse-json' );
var reviveBasePRNG = require( '@stdlib/random-base-reviver' );
// Progress the PRNG state...
var r1;
var i;
for ( i = 0; i < 100; i++ ) {
r1 = randu();
}
// Serialize the PRNG as a JSON string:
var str = JSON.stringify( randu );
// Revive the JSON-serialized PRNG:
var rand = parseJSON( str, reviveBasePRNG );
if ( rand instanceof Error ) {
console.error( rand.message );
}
// Generate duplicate sequences...
var r2;
for ( i = 0; i < 100; i++ ) {
r1 = randu();
r2 = rand();
console.log( '%d == %d ? %s', r1, r2, ( r1 === r2 ).toString() );
}
