小于1mb时的PHP数字格式

Question

Hope someone can figure this one out.

I'm using this to display the filesizes of several files in a folder...

number_format (round (filesize($currentfile) /1048576)) . "mb"

...which displays my file names like this:

27mb
35mb
10mb

etc.

But, if the filesize is less than 1mb, it displays onscreen as:

0mb

How can I modify the PHP so that if it encounters a 250k file for example, it shows displays as ".25mb"?

Thanks in advance.

Well you just need to check if it is below 1MB and handle it differently.

number_format (filesize($currentfile) / 1048576, (filesize($currentfile) < 1048576 ? 2 : 0)) . "mb"
