reviveBasePRNG
Revive a JSON-serialized pseudorandom number generator (PRNG).
Installation
npm install @stdlib/random-base-reviver
Usage
var reviveBasePRNG = require( '@stdlib/random-base-reviver' );
reviveBasePRNG( key, value )
Revives a JSON-serialized pseudorandom number generator (PRNG).
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()
.
Examples
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() );
}
