Hi experts

I am making a program which needs to calculate some numbers.

When the user input some very big numbers, the calculation may cause OVER FLOW and the program stopped!

How can I detect the calculating result will be over flow and avoid the program stopping?

Always work with variables big enough to receive the biggest possible value. You should use double or currency variables.

Hi Waty

In my program, no matter what variables type I use, a user can always causes a over flow result. That is because the user doing something wrong and the program may not stop the user doing so.

You could limit the entry at 10 characters (for example).
