jamesrandom

JamesRandom Module

This pseudo random number generator have been written in JavaScript in order to bring a better mathematical behavior that it is present in Math.Random built in function.

JamesRandom is based on CLHEP - A Class Library for High Energy Physics, which is written in C++. This JamesRandom written in JS does not have all the functions that have JamesRandom CLHEP, but it does what it must to do, i.e. generates random numbers (by default between 0 and 1).

One way to use it is:

    var JamesRandom = require('jamesrandom');
 
    var gen = new JamesRandom({seed: 12345});
    var A = [];
    var sizeA = 40;
    gen.FlatArray( sizeA, A );
    console.log(A);

Public Functions

Name()

Returns String "HepJamesRandom".

Flat()

Returns one pseudo random number between 0 and 1.

FlatArray( size, vect )

Where size is an integer and is intended to be the size of the array vect of pseudorandom numbers.

SetSeed( seed, dum )

Where seed is an integer and dum is another integer generally 0.

SetSeeds( seed, dum )

Where seed is an integer and dum is another integer generally 0.
