WebWhen you need to sqrt, sin, cos etc. then convert to long double, divide by 1000, sqrt, multiply by 1000, convert to integer. The differences between machines should not matter then. You can use another scale for faster divides, for example 1024 as x/1024 == x >> 10. Web6. Changing fixed point representations is commonly called 'scaling'. If you can do this with a class with no performance penalty, then that's the way to go. It depends heavily on the compiler and how it inlines. If there is a performance penalty using classes, then you need a more traditional C-style approach.
