!Random commentStamp: 'ul 2/20/2015 09:44' prior: 0! I implement the 32-bit version of the Mersenne Twister PRNG, using 30-bit arithmetic, based on http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/ARTICLES/mt.pdf . The parameters of the generator are stored in class variables prefixed with MT.
Instance Variables states: <Array> index: <Integer>
index - the index of the state, which should be used to generate the next random integer value
states - an Array holding the internal state of the generator

If you just want a quick random integer, use: 10 atRandom Every integer interval can give a random number: (6 to: 12) atRandom SequenceableCollections can give randomly selected elements: 'pick one of these letters randomly' atRandom SequenceableCollections also respond to shuffled, as in: ($A to: $Z) shuffled
The correct way to use class Random is to store one in an instance or class variable: myGenerator := Random new. Then use it every time you need another number between 0.0 and 1.0 (excluding) myGenerator next You can also generate a positive integer myGenerator nextInt: 10!
