I'm fairly experienced in ANSI C. I actively program microcontrollers for robots. This requires an immense amount of mathematical operation, as does most programming. But Cocoa doesn't seem to support even the most simple mathematical operations. So, can someone tell me how to perform mathematical operations in Cocoa? I have tried to make an application that adds two number together. I made an interface that that consists of three text fields, two for the numbers being added, one for the sum, and a button to initiate the calculation. But that as far as I got.
