The Central Randomizer has an excellent random number generator for public domain use (as long as it remains unchanged):
<SCRIPT>
<!--
// The Central Randomizer 1.3 (C) 1997 by Paul Houle (houle@msc.cornell.edu)
// See: http://www.msc.cornell.edu/~houle/javascript/randomizer.html
rnd.today=new Date();
rnd.seed=rnd.today.getTime();
function rnd() {
rnd.seed = (rnd.seed*9301+49297) % 233280;
return rnd.seed/(233280.0);
};
function rand(number) {
return Math.ceil(rnd()*number);
};
// end central randomizer. -->
</SCRIPT>To use the Central Randomizer code, ensure it is placed between the <HEAD> and </HEAD> HTML tags.
To create a random floating point number use: rnd(), to create a random integer, say between 1 and 10, use rand(10).
