long a; // Declare variable 'a' of type long
a = 23; // Assign 'a' the value 23
long b = -256; // Declare variable 'b' and assign it the value -256
long c = a + b; // Declare variable 'c' and assign it the sum of 'a' and 'b'
int i = (int)c; // Converts the value of 'c' from a long to an int
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.
long var = value
||variable name referencing the value
||any integer value
