I do not know if this is a bug or a case of improper documentation. The documentation for formatC() implies that the difference between the options format="f" and format="g" is that with "g", scientific format is sometimes used. There is another difference between them that is not mentioned in the documentation. drop0trailing=FALSE is ignored when format is set to "g" unless flag contains "#" (this is the documented behavior for format="fg"). For instance, the first line below return " 2.5", whereas the second returns the expected "2.50".
