Hi !
I'm using the printImageMetadata() function to display exif.

This works fine but sometimes the aperture value is display with an useless accuracy, for instance f/1,3999999761581 instead of f/1.4

How can I round these values ?

Make a custom function.

Al-right I will do that but this could be an improvement for next release.

FxIF, a firefox extension that allows you to view exif informations, displays properly the aperture value for the same image.

WEll, Zenphoto displays the value as it is recorded. WHich is what most people expect. Anyway, feel free to open a ticket about so we might look into this some time.

line 414 of exif.php is where this value is generated. You can add a round() function call to the code.
