Google’s search-based calculator is a bit of a God-send when it comes to impromptu math, but now the Big G has gone and extended its functionality by rolling out a full-on, 34-button scientific calculator.
It’s got everything you really need in a calculator, numbers aside: trigonometric functions, logs, powers, pi, Euler’s number and even factorials (that’s the exclamation point, if you dropped out of math classes early). Just type in any calculation—something as simple as 2+2 will do—and up it pops.
It's my life, you're just along for the ride! 
but now the answer is in a field which makes it harder to select/copy for pasting elsewhere
That’s true hadn’t thought about that!
