i modified my calculator by doing some adjustments which makes it more in a mathematic style. The adjustments i'm talking about are the floating symbols and the VC which signifies (Vianey's Calculator). Who is Vianey : vianey is no one else than me the creator of this calculator . Why did i wrote my name initiales : because i wanted to leave a mark showing it's me who created and to have something reflecting me which every one can see and know the creator. Thanks.nks.
