Here is the latest report that Google have just added the calculator of 34 button to its search results and this was firstly reported by The Verge.
This was announced by Google through their official twitter account and according to their tweet “New data refresh of Panda starts rolling out tonight. ~1% of search results change enough to notice. More context:http://goo.gl/huekf “
CNET claimed that When you type a formula into its search box, Google now will spit out the answer in a new calculator that it has brought to its results.
Once the calculator is displayed, you can tap numbers and scientific functions to send it a new equation. The search box will also still work for that.
Prior to this addition, Google allowed users to type any equation into its search tool. The search engine would then spit out the answer. However, this is the first time that Google has displayed an actual calculator users can interact with.
