The double is a fundamental data type built into the compiler and used to define numeric variables holding numbers with decimal points. C, C++, C# and many other programming languages recognize the double as a type. A double type can represent fractional as well as whole values. https://www.quora.com/In-C++-what-does-a-double-do https://www.thoughtco.com/definition-of-double-958065
