Arithmetic operation resulted in an overflow

[randmeer]

Hello,

I am trying to make a little program, but I face a problem as described below.
Value-1 and Value-2 are data type short, Answ is data type integer; big enough to contain the answer of the multiplication of value-1 and value-2. But still I got an error message after the multiplication. If I change value-2 into data type integer everything goes alright.


Why? Can anybody help me?


Dim value-1 As Short = 165
Dim value-2 As Short = 2400
Dim answ As integer

Answ = value-1 * value-2

Reports the following error:
Additional information: Arithmetic operation resulted in an overflow.
In the debugger:
Constant expression not represent able in type 'Short'.


Thanks in advance

It's actually normal because the compiler will first set aside a short to store it's result and then cast that to an integer.

Did you try them as integers or casting them to integers before doing the operation?

Okay, I understand. Casting to integers works fine.

Thanks a lot.
