too many digits behind comma

[DwarV]

i have this script that calculates the file size in kilobytes..
by deviding the calc_size (in bytes) by 1024... :

$calc_size = ($_FILES['userfile']['size'] / 1024);

this works..
the result is (for instance) 0,333333333

my question:
how to get rid of those digits behind the comma and
make it print like 0,33
?

you need to define the variable after the math ops... like so:

$calc_size = number_format($calc_size,2);

where 2 is the number of digits after the comma

hope it helps
