||Datatype for large integers. While integers can be as large as 2,147,483,647 and as low as -2,147,483,648 (stored as 32 bits),
a long integer has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (stored as 64 bits).
Use this datatype when you need a number to have a greater magnitude than can be stored within an int.
Processing functions don't use this datatype, so while they work in the language,
you'll usually have to convert to a int using the (int) syntax before passing into a function.
