I don't know what your cursus and/or specilities and I really don't care as far it's not the discussion. But you use php as a programming langage (yes it is), the problem with scripting langage for the web is the common people thinks cool, easy langange, easy learning curve, I am a programmer. In their dreams...MS meats the same problem with VB.
You have to understand basic concepts before starting to learn a programming langage (I dont talk about design and so on....), one of them is how to work with floating numbers. A lot of people told you the how and why. You still cry about blah blah and blah. Take the all current thread, read it, follow the links (google), and come back if you find a real problem with php and floats.
