Thx. I tried
(setf a (round 2.1))
and it works.
I was just confused by the TWO return value.
What should I do, if I want to capture these 2 value in 2 different variable by using "round"?

I thought the function 'round' might work, but it fails to do what I want.
Neither does 'coerce'. So I'm wondering is there any built-in function that works on this, say convert 2.1 to 2 and 2.9 to 3?

Thanks for answering a newbie's question.
