Overflow
 

Excel 2003 SP2





Hello every body


This little sub gives me a runtime overflow. Did I miss something?




Sub ebj()

Dim ll_test As Long

ll_test = 162 * 207


End Sub



I would have expected ll_test to take a value = 33,534. A Long should be
sufficient to hold that. If I change the declaration to Single or Variant I
still get an overflow.



Any suggestions?





Best regards

The problem is that VBA tries to calculate
162 * 207 as an Integer, and then convert
to the result to a Long. The first of these
steps causes the overflow. You can get
round this by forcing one of the values
to be a Long:

ll_test = 162& * 207
or
ll_test = CLng(162) * 207

Note that ll_test = clng(162 * 207) will fail,
for the same reason as in the original problem.
