Divided by zero

=IIF( Fields!DAILYRUNRT.Value > 0, Fields!DAILYRUNRT.Value /
Fields!GOL_DAILYRUNRT.Value * 100, 0)
Why this is throwing Divided by zero error
please help meBecause GOL_DAILYRUNRT.Value is zero? Perhaps you should put
IIF( Fields!GOL_DAILYRUNRT.Value > 0, Fields!DAILYRUNRT.Value /
Fields!GOL_DAILYRUNRT.Value * 100, 0)?

check if that is greater than zero.
Try this:
=IIF( Fields!GOL_DAILYRUNRT.Value = 0 ,0,Fields!DAILYRUNRT.Value/ IIF(
Fields!GOL_DAILYRUNRT.Value = 0,1, Fields!GOL_DAILYRUNRT.Value)
In any case, IIF is a function call and therefore all arguments are
evaluated before the function is invoked( which causes the division by zero
in expression).

I have tried your expression as it is a more elegant solution to this
nagging problem than I have been using. Of course in my tests this morning I
could not get the simple expression IIF(FieldB.Value = 0, 0, FieldA.Value /
FieldB.Value) to fail. It returned zero instead of #error, NaN, infinity....
It seems as though RS evealuate both sides of the IIF statement sometimes
and only one side on other occassions. There seems to be no consistency at
all that I can figure out, however, I will definitely try your expression the
next time I need to code around this issue. Thanks for the posting.

globally solve this for your whole report with a function like this:
Function SafeDivide(byval onumer as Object, byval odenom as Object) as
Decimal
' author: jerry nixon
' purpose: divide and avoid div by zero errs
' version: 1.4
If onumer Is Nothing Then Return 0
If odenom Is Nothing Then Return 0
If isDbNull(onumer) Then Return 0
If isDbNull(odenom) Then Return 0
Dim inumer As Decimal
Dim idenom As Decimal
Try
inumer = Ctype(onumer, Decimal)
idenom = Ctype(odenom, Decimal)
Catch ex as Exception
Return 0
End Try
If Not isNumeric(inumer) Then Return 0
If Not isNumeric(idenom) Then Return 0
If idenom = 0 Then Return 0
Try
Return Decimal.Divide(inumer, idenom)
Catch ex As Exception
Return 0
End Try
End Function
