Google search has long featured a built-in calculator function but a recent update added a fully functional 34-button scientific calculator. Previously, when a user entered, say, 2+2, Google would simply display the sum above the search result. Now, when that equation is entered into the search bar, the answer pops up along with the new calculator. Best of all, this works in mobile browsers and voice search, too.
This isn’t a stripped down calculator, either. It’s a full-power, voice-enabled scientific calculator with nearly all the functions of a tangible model. Plus, it doesn’t require two AAA batteries. A Google Product Manager pointed out in this post’s comments that the scientific functions appear when the phone is rotated to be viewed in a landscape mode.
