> Suppose X = 7394; and you'd like to compute how many megabytes X
>evaluates. You'd probably use X / 1024 which will yield: 7.220703125.
>
> Question is: how can you limit the digits after the period, lets say 3
>digits, so the above answer would be: 7.220 = 7.22.
$M = (float) sprintf("%.2f",$X/1024);
(the float casting is not really necessary).
