Maybe something nice to build with Pythonista?
Ideas of which classes one needs ... and then and building it 'testdriven' with unittest

Have a look here

Picture of to be done Calc added and info how to get the code added.
Will go to github, if updated ..
Why my wiki? If someone is interested, he/she could get a password to
edit that page ...(or related ones if needed). On git I do not know how to make that possible ... otherwise git would be as nice ...
Update: inverse sin (asin) etc. and 'deg <-> rad' computations
Next idea: make it so (Peter!), that programming will be possible ;-)
