An almost complete implementation in JS of the java.util.Random class
from J2SE, designed to so far as possible produce the same output
sequences as the Java original when supplied with the same seed.
usage:
let Random = require('java-random');
let rng = new Random(1);
let val = rng.nextInt();
The functions implemented with direct equivalents are:
setSeed(seed)
nextInt()
nextInt(bound)
nextBoolean()
nextFloat()
nextDouble()
nextBytes(bytes)
nextGaussian()
NB: the seed value supplied in the constructor or via setSeed is
limited to a maximum of 52 bits (i.e. Number.MAX_SAFE_INTEGER).
The functions that return a Stream are replaced with JS generator
functions:
ints()
ints(streamSize)
doubles()
doubles(streamSize)
The functions that generate long values are only available on JS
platforms that are able to return a 64-bit BigInt instead of a
Number (e.g Chrome 67+, Node.js 10.4.0+):
nextLong()
longs()
longs(streamSize)
The functions not implemented are:
ints(randomNumberOrigin, randomNumberBound)
ints(streamSize, randomNumberOrigin, randomNumberBound)
doubles(randomNumberOrigin, randomNumberBound)
doubles(streamSize, randomNumberOrigin, randomNumberBound)
longs(randomNumberOrigin, randomNumberBound)
longs(streamSize, randomNumberOrigin, randomNumberBound)
