My target was to make a smart calculator only using vanilla JavaScript. Until this commit this calculator was fully working only on vanilla JavaScript.

I always tried to fix the fractional calculation issue (like 0.1 + 0.2 = 0.30000000000000004). I've implemented many changes and spent lots of hours sitting next to my pc for solving that calculation issue. My first try to solve the issue was on April 14, 2021. I spent my valuable time in solving that issue last on 5 & 6 March, 2022. All these hard works & my precious time didn't paid off because the issue didn't totally wiped off. I had managed to solve the issue in multiplication & division but there were still issues in addition & subtraction. See the code of how I tried to solve the issue using vanilla JavaScript, here

At last, I gave up & search in google for any permanent solution. I found mathjs library & implemented it on this calculator on March 7, 2022. Finally, I hope the calculation issue has been solved.
