Question
I have a macro that has the statement:
If X <> 0# Then
If I output the value of 0# it comes up as zero.
Any idea why this is there like that?
Ian,
It is zero.
You can check out the purpose in the immediate window in the Visual Basic Editor:
? typename(0)
Integer
? typename(0#)
Double
so you can see that the # casts the zero constant as a double.
This might be appropriate if X is typed as double as well. You can think of it as explicit casting - since if you don't, excel/vba will have to do an internal conversion to do the comparison if the types are not of equal type. In actual practice, it might not make any difference in how the code executes.
