Code for the computer scientists calculator
The computer scientist calculator is a modern take on the HP 16C. It was born out of frustration of the terrible windows calculator, and since it's aimed at EE's, it also has to have hardware.
The software is in a semi-stable phase at the moment. The core of the calculator, the software/comSciCalc_lib has had the ground work made. Fluffy features such as doxygen and clang formatter has been added as well.
