Google now display mathematical results on a calculator!!

Earlier when we had to get answer to a mathematical calculation, we type in the expression in the search box and we get the answer in the results page in bold letters as the first result. But now Google has introduced a virtual calculator on the results page which would display the result of our expression. And if we want further more calculations to be done, It can be done on this same calculator, as we use other calculator applications on our system.
This virtual calculator consist of the basic mathematical functions along with the trigonometric functions and logarithmic functions. It also works on mobiles, other web browsers as well as on ios and android.
