I don't know how many of you use the iOS Calculator app, but if you do, then you've probably already discovered that it has a hidden function thought out by Apple. The function can be used based on gestures and practice allows us to delete the decimals using simple swipes. If you look at the video clip above, you will notice that a simple side swipe, carried out above the field where the numbers are displayed, deletes the decimals without much effort, everything being available in the application for several years.
