Multi-purpose calculator for mobile web (Annuity) with source code

Hello,

I made breakthrough yesterday. My productivity exploded.
I made Excel-like calculator, allows you to calculate discount rate really easily.

If you want to calculate annuity for three years, just type like

1/1.03 + 1/1.03^2 + 1/1.03^3

I have been in search for this type of calculator, but I couldn't

I really take care of user experience. If any kind of problems that you have, please, let me know.
I made this while I am studying CFA and AICAP. I hope it would help you a lot study finance.

It also has a function that stores the variable that you want. You can repeat the variable. Press "V" button when you want to repeat the variable. It really helps when you calculate NPV.

Source code is available in my github website.

[Bug fixed-04/10/2016]
- It doesn't recognize "e^(-3)". I fixed it with simple string manipulation
- I don't have a great idea how to calculate "ln(2)" in the stack calculator. Please, someone gives me a great idea.
