VB Function Round vs Excel function Round not behaving the same Od
 

Here how it goes :

Have a VB function :

Public Function MyRound(Data)
MyRound = Round(Data, 1)
End Function

Have a excel sheet with cells on one side with the "MyRound" function and on
the other side the Round function from Excel, guess what they don't give the
same results.

Here the example :
Data Fonction Round Round Excel
=Myround(A1) =Round(A1;1)
0,15 0,2 0,2 Ok
0,25 0,2 0,3 Wrong from VB
0,35 0,4 0,4 Ok
0,45 0,4 0,5 Wrong again From VB

My understanding of the error is : don't have an odd number with an even
one, VB will not round your numbers ????

I've tried this with Excel 2003 and 2000, same results.

I'm asking Microsoft to post a official answer to this and also posting a
bug report for it, and to give a fix.

Thanks and lookout for those even numbers !! Don't you find this Odd ??

Use this:

Public Function MyRound(Data)
MyRound = application.Round(Data, 1)
End Function

VB Function Round vs Excel function Round not behaving the same Od
 

Hey bud.

VBA is a separate application from Excel. Excel just uses VBA as its macro
language, same as Word, Powerpoint, Autocad, Corel Draw and others.

The round function was introduced in VBA in version 6 - first used in
xl2000.

This was addressed back then and is by design. There is no reason to expect
that the VBA round function would round the same as Excel. Different
products, different rules.

Thank you for the reply, very usefull !!

It would have been nice from microsoft to include such information in the
help of VBA in office 2003, since it has been know for a while...

The help is not explicite on how it is rounding numbers.
(banker's rounding, Its funny)

VB Function Round vs Excel function Round not behaving the sam
 

What MS calls "banker's rounding" has been considered best practice for at
least a century, and is specified by ASTM, IEEE (in its binary equivalent)
and many other standards bodies.

It is sometimes called "unbiased rounding" because it rounds to the nearest
rounded number with ties going up or down to make an even rounded number,
thus avoiding the small bias introduced by always rounding 5's up.

What does strike me as funny is how it ever came to be called "banker's
rounding" since as far as I can tell, banking and finance is about the only
area where it seems to never be used.

May be it's a case of the banking sector saying that they utilise this
unbiased rounding when in practice they didn't. Then pocketed the
difference.
