What is difference between double and float?
While float has 32 bit precision for floating number (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision. As double has more precision as compare to that of flot then it is much obvious that it occupies twice memory as occupies by the float data type.
