random( )	Firefox/Netscape/NN 2 IE 3 ECMA 1

Returns a pseudo-random number between 0 and 1. To calculate a pseudo-random integer between zero and another maximum value, use the formula: Math.floor(Math.random( ) * (n+1))
where n is the top integer of the acceptable range. To calculate a pseudo-random integer between a range starting with a number other than zero, use the formula: Math.floor(Math.random( ) * `n` - m + 1) + m
where m is the lowest integer of the acceptable range and n equals the maximum value of the range. Note that the Math.random( ) method does not work in the Windows and Macintosh versions of Navigator 2.
