Help - Glossary - R - Random
Squeak has a (pseudo) random number generator. Select the following three lines and do Cmd-p:
| pseudoRandy |
pseudoRandy := Random new.
pseudoRandy nextInt: 100. "Produces a pseudo-random integer between 0 and 100, not including 0".
Using Cmd-p and Cmd-z alternating you can test this out. (You can also replace 100 by another integer.)
The term "pseudo" means that the integers produced mimick the behaviour of true random series, but don't quite succeed, in the long run. If you consult the class Random (select and use Cmd-b) you find the code and some explanations.
