I like that you can use it to solve general equations, calculate values of pi or any other mathematical expression at any point in time through out your programing without having to constantly redo calculations everytime there's an update.The input screen makes coding very efficient because all information required by the equation are right next to eachother so no more searching around my code when i'm trying to find what number goes where. It isn't really much but sometimes some minor bugs will show up after running this software over many hours. But as long as everything works fine its ok. Using this math library has made our jobs so much easier especially since we're doing engineering work which uses formulas alot!
