Navigator 3.0; buggy in Internet Explorer 3.0; Unix platforms only for Navigator 2.0

`Math.random()` returns a psuedo-random number between
0.0 and 1.0. Note that in Navigator 2.0, this function only
works for Unix platforms. In Internet Explorer 3.0,
`Math.random()` generates pseudo-random numbers, but is
not randomly seeded, so it generates the same sequence of numbers each
time the browser is started.

Since `Math.random()` does not work on all
platforms, you should not rely on it if you
want your scripts to be really portable. If you need only a single
pseudo-random number, you can often use a portion of the
current time, such as `(new Date()).getSeconds())`.

If you need need a sequence of more reliably pseudo-random
numbers (for a game, perhaps), you'll have to write your own
pseudo-random number generator. The following code
is based on a linear congruential algorithm in the book
*Numerical Recipes*, and produces simple,
non-cryptographic, pseudo-random numbers:

function random() { random.seed = (random.seed*random.a + random.c) % random.m; return random.seed / random.m; } random.m=714025; random.a=4096; random.c=150889; random.seed = (new Date()).getTime()%random.m;

Internet Explorer 3.0 does not randomly seed its random-number generator, so it generates the same sequence of random numbers each time the browser starts up. This bug will be fixed in a future release.
