## Error in binary arithmetics

Hello everyone !
I got a problem, I can't figure out why when I compute $A+B$ and $2\times (\frac{A}{2}+\frac{B}{2})$ the result is sometimes different.
Can anyone explain why the results of the two operations are different ?

Edit : A and B are coded in binary of course and we compute a binary addition.

 Integers I forgot to mention sorry.

Well there ya go.

Got Basic?

FOR I = 1 , 10 , 1
PRINT I, INT( I/2)
NEXT I
END
