Code.SafeDivide Expression

What does =Code.SafeDivide mean in an expression? I have an example below:
=Code.SafeDivide (Sum(Fields!revenue.Value), Sum(Fields!volume.Value))
Thanks, DeborahThe only time I've seen something like that is when you write a custom
code function called "SafeDivide". This will do a check on the divisor
(the second parameter) and, if it is 0, it will not perform the
division. It will just return 0. Here is an example I found (this
example will actually take a 3rd parameter - the "value if undefined"
parameter):
The following was snipped from this thread. Read it to see the full
explanation:

Public Function SafeDivide(pi_dblNumerator As Double, pi_dblDenominator
As
Double, pi_dblUndefined As Double)
If pi_dblDenominator = 0 Then
SafeDivide = pi_dblUndefined
Else
SafeDivide = pi_dblNumerator / pi_dblDenominator
End If
End Function
