Originally reported on MediaWiki.org:

The digital format for "Views per edit" in "View statistics" not displayed correctly for non-English.

Problem in includes/HitCounters.body.php:

		['hitcounters-statistics-views-peredit'] =
			$contLang->formatNum( $totalViews
				? sprintf( '%.2f', $totalViews / SiteStats::edits() )
				: 0 );

: [de] "Aufrufe pro Bearbeitung" shows "21.28", should be "21,28".
: [es] "Visualizaciones por edición" shows "40 16", should be "40,16".

This seems to work:

		['hitcounters-statistics-views-peredit'] =
			$totalViews
			? sprintf( '%.2f', $totalViews / SiteStats::edits() )
			: 0;
