what is a float or long

[akasoldats]

I've started reading a book about android development. In one of the exercises it asks the reader to declare either a float, long, string, integer, or a boolean. I know what the last three would be used for but dont exactly understand what the first two are. Could someone give me a definition on what they would be used for?

When using decimals you are better off using double instead of float, especially if many calculations are going to be made and precision is of importance. Also I do believe that most processors are optimized to handle doubles with greater efficiency.

An integer is always going to be the size of the processor's register...so 32bit cpus will have 32bit integers and so on.
