Python numeric objects are basically numbers. With the exception of Boolean, the numeric types of int, long, float, and complex are all signed, meaning they can be positive or negative. Boolean is a subclass of the integer that can be one of two values: 1 for True, and 0 for False. The rest of the numeric types are differentiated by how precise they can represent the number; for example, int are whole numbers with a limited range while long are whole numbers with unlimited range. Float are numbers using the double-precision representation (64-bit) on the machine.
