Steps to Reproduce:
- Request https://en.wikipedia.org/w/api.php?action=query&prop=imageinfo&iiprop=metadata&titles=File:Hummingbird.ogv approximately 15-20 times and note the value of the length property each time
- The length value reported is most often 20.754066666667 (precise to 12 places after the decimal point), but occasionally 20.754066666666667 (precise to 16 places after the decimal point).
- When the same request is directed to Commons (https://commons.wikimedia.org/w/api.php?action=query&prop=imageinfo&iiprop=metadata&titles=File:Hummingbird.ogv), the value appears to be consistently reported as 20.754066666666667.
- The value is reported with the same precision across requests and is consistent with the precision when requesting from the file's native repo
