Version 2.7

Important update !! First, big thanks to n0tkamui for helping me with some things and rewritting some part of the code!!
So here's all what's new :

Added some maths operators (and a constant) :

"!" wich is the factorial operator (i.e 5! is equal to 120) It is used after a number
"%" (he made a comeback 🗿) wich is a percentage operator (i.e 10% is equal to 0.1) It is used after a number
"√" wich is the square root operator (i.e √10 is equal to 3.16) It is used before a number
"π" wich is equal to aprox ~3.14159

The deciaml formatting is now set to a comma after every thousands (every 3 numbers). The switch to enable / disable it was removed :

301457.82 -> 301,457.82

Operator are now created in Evaluator.kt with Keval to make calculations faster

Re-added SplashScreen for all versions of Android

For the dev part

#56 Stopped .idea and .gradle from being pushed to code. These are simply settings files for the IDE and gradle cached files.
#57 #58 Commits will now only be pushed to GitHub once the final APK of a version is compiled, there shouldn't be anymore none matching commits.

Thanks for using CuteCalc ❤️ !!!
