Definition: A double is a larger float type that holds both bigger and more precise numbers.
Double variables are 8 bytes in size. The range of values is from 2.2250738585072020×10−308 to 1.7976931348623157×10308
More importantly, the precision of a double is 15 compared to 6 for a float. The precision of a number is how many digits (before and after the decimal point) it can store without errors occurring.
