Numbers in the EXIF data block on image description pages are always rendered in English format instead of the format of the user's preferred language.

The relevant code seems to be function formatNum on line 1082 of Exif.php, which is

01082 function formatNum( $num ) {
01083 $m = array();
01084 if ( preg_match( '/^(\d+)\/(\d+)$/', $num, $m ) )
01085 return $m[2] != 0 ? $m[1] / $m[2] : $num;
01086 else
01087 return $num;
01088 }

It rather should be

01082 function formatNum( $num ) {
01083 global $wgLang;
01084 $m = array();
01085 if ( preg_match( '/^(\d+)\/(\d+)$/', $num, $m ) )
01086 return $wgLang->formatNum( $m[2] != 0 ? $m[1] / $m[2] : $num );
01087 else
01088 return $wgLang->formatNum( $num );
01089 }

Thanks
