WebYou can't convert a float to an int. An int has no decimal portion so part of your float value gets lost. Your compiler will warn you about this. If you ignore the warning then any bad things that happen later will not be the compiler's fault. You can however convert an int to a float with a zero decimal portion. But you can't convert it back.
