Question

While working away on an old piece of code I came across something like this:-

Public Function MyFunc (some parameters) As Single

    If some condition Then
        MyFunc = calculate some value
    Else
        MyFunc = MyFunc
    End If

End Function

I’m rather hoping to regularise the second leg of that test; would I be right in assuming the returned value is 0.0 if some condition is false?

Answer 1

Yes, for a function with a defined return type then the default return value is the default for that type (0 for numerics etc) just as if the code contained a Dim MyFunc as Single at the top.

If no type is specified and no value is implicitly returned, then the Empty value is returned.
