[Data Types]


Long variables are extended size variables for number storage, and store 32 bits (4 bytes), from -2,147,483,648 to 2,147,483,647.

If doing math with integers, at least one of the numbers must be followed by an L, forcing it to be a long. See the Integer Constants page for details.


long var = val;

var - the long variable name val - the value assigned to the variable

Example Code

  long speedOfLight = 186000L;   // see the Integer Constants page for explanation of the 'L'
