$pathsize="some path to the file here";
$size=filesize($pathsize);
$size=$size/(1024*1024);
well that's the way i use to turn the bytes in megabytes, but the problem is that $size becomes a number with, 14 signs after the decimal point
i need they be only two,
so i need a way, to control the echo output of $size and make it show only 2 signs after the decimal point, or if there is a pre-made function showing the size in MBs, will be even better
