random() and randomg() pseudo-random number generators

This page is for the current JSim version 2.0. Click here for the earlier JSim 1.6 version.

This document describes the syntax and use of the random() and randomg() pseudo-random number generators. (MML).

Prerequisites:

Contents:

random() syntax

The random() function generates a pseudo-random number from a uniform distribution between 0 and 1 inclusive.

Syntax for generating a real number between 0 and 10:

      real var, var2;
      var=10; 
      var2 = var*random(); 
To set 'seed' value for random number generation:

randomg() syntax

The randomg() function generates a pseudo-random number from a Gaussian (normal) distribution of mean 0 and standard deviation 1.

Syntax for generating a real number between 0 and 10:

      real var, var2;
      var=10; 
      var2 = var*randomg(); 

random() and randomg() examples:
