Whats the difference between a single precision and double precision . . . The term double precision is something of a misnomer because the precision is not really double The word double derives from the fact that a double-precision number uses twice as many bits as a regular floating-point number For example, if a single-precision number requires 32 bits, its double-precision counterpart will be 64 bits long
What exactly does Double mean in java? - Stack Overflow A Double in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double object
