It misinterprets "log(64!/32!, 2)" as "log(((64!) / (32!)) .2, 10)" which seems absurd, why would you use the comma as both an argument separator and a decimal place??
(Why was I using DuckDuckGo as a calculator? I do in fact keep a Casio scientific calculator on my desk, but I recently bought a new one (a Casio fx-991cw) so that I wouldn't have to keep moving the first one between home and work, but the new one doesn't have an obvious factorial function and I gave up looking - it is much worse than my fx-991es in many other ways as well despite looking superficially newer and better, so I can not recommend the fx-991cw).

Oops! Thanks, the issue was with DuckDuckGo's calculator which I mistakenly trusted:
