What the ...?!?
/= ?
You divide the value of $var by 1024, assign it back to $var, divide
it by another 1024, assign it again to $var, then format the
resulting number using sprinf() and assign it to $var?!? Why???
$var = sprintf ("%.2f", (($var / 1024) / 1024));
will do the same as will
$var = sprintf ("%.2f", $var / (1024*1024));
And it will be more efficient because the multiplication will be done
at compile time (once) and you'll only do a single division each
time. Which is also more precise, though in this case it doesn't seem
to matter.
