I decided to uninstall rEFIt since I had no need for it. So I followed the instructions here …

What happens when you set an int or double value to less than the minimum? I need my program to recognize when a number is smaller then the minimum, and then set the value to equal the minimum instead. This behavior is not the default... [CODE]#include <iostream> using namespace std; …
