# NES Calculator

This is a scientific calculator for NES, based on http://www.crbond.com/calc65.htmand inspired by this tweet.

## Controls:

**D-Pad:**move the cursor**A**: press the currently selected button**B**: toggles between exp and log functions, between square and square root functions, and between normal, inverse, hyperbolic and inverse hyperbolic trigonometric functions.

## Notes:

- The input is always in scientific notation. The last 3 digits on display are the current exponent. Therefore, if you type 413 it will be displayed as "4.1300000 002" (meaning 4.13 x 10
^{2}) - The mantissa has 10 digits of precision. The last 2 digits aren't shown but they can still be inserted.

Not many emulatable utilities, commercial or homebrew, so thanks for making another one! I've added it to the list on my wiki: https://wiki.funkey-project.com/wiki/List_of_emulatable_utilities#Calculation
