Evaluating {{#expr: 1 round 11}} on Wikimedia wikis gives "1.00000002048" (error: ~2e-8) instead of "1". I noticed a similar problem for other integers or floating-points numbers < 1000, for precision 11, 12 and 13. I tested this on fr.wikipedia.org, en.wikipedia.org and test.wikimedia.org. On a local installation of MediaWiki after syncing MediaWiki and the ParserFunction extension at git head (configuration: 32-bit, Ubuntu, PHP 5.5.9), I cannot reproduce this issue (I get "1" as expected). (this bug has been reported on https://fr.wikipedia.org/wiki/Wikip%C3%A9dia:Le_Bistro/3_d%C3%A9cembre_2014#round)
