Description   Datatype for floating-point numbers, a number that has a decimal point. Floating-point numbers are often used to approximate analog and continuous values because they have greater resolution than integers. Floating-point numbers can be as large as 1.7976931348623157E+308. They are stored as 64 bits (8 bytes) of information.
