Several people rightly suggested -int()-.
Of interest here -- and in related problems --
is the introduction in Stata 8 of -floor()-
and -ceil()- (ceiling) functions. For ages,
-floor()- and -int()- will agree, but one
small point is that the floor and ceiling
terminology for rounding down and up --
due to Kenneth E. Iverson in the early 1960s --
is easy to learn and remember, especially if you
have not memorised _exactly_ what -int()-
does.
