[mso] Re: EXCEL ROUND DOWN FUNCTION

All--

For what it's worth: since David's original post seemed to indicate to
me that he was aking about the correct use of the ROUNDDOWN function,
rather than which use of the SUM function was more syntactically
correct, I merely wrapped his example SUM(C10)+(E10)+(G10) inside the
ROUNDDOWN function. I've found that sometimes it's best to deliver only
what is asked for. Nothing more, nothing less.

I was going to mention the "incorrectness" in the format of these
formulas also, but I figured I wouldn't nitpick.

But, while we are at it, I will add a "correction" to what Andrew says
also....he says: the SUM(<range>) function should ONLY be used for
adding a range of contiguous cells

Which is not technically correct either....SUM can be used for
noncontiguous cells also, if you just separate them with commas...for
example,
=SUM(A1,B15,D33,F96) is a perfectly acceptable formula.  It can even
include ranges as well as noncontiguous cells, like this
=SUM(A1,B15,C22:C55,F12)

So, if I were doing the rounddown formula shown below, I would format it
this way:
=ROUNDDOWN((SUM(C10,E10,G10)),0)

Different strokes, eh?

David,

Although
 =ROUNDDOWN(SUM(C10)+(E10)+(G10),0)
works and gives the correct answer, it is actually incorrect syntax.
I'm surprised that noone gave you the correct formula.

 =rounddown(c10+e10+g10,0)
would be correct.

It's arguably a minor point (if a formula works, then it works) but you
should understand that the SUM(<range>) function should ONLY be used for
adding a range of contiguous cells, e.g. =SUM(A1:A100).  It is NOT
required (as many people seem to believe) to introduce any formula.

I regard the fact that, for example =SUM(A1*B1) works, as a bug in
Excel; it should give an error.  I have a lot of students who make this
mistake.  In the OCR New CLAIT exams it is considered acceptable but at
the higher level of CLAIT Plus it is marked as an error.

all the best,

Andrew Kendon
