long

Description

If doing math with integers at least one of the values must be of type long, either an integer constant followed by an L or a variable of type long, forcing it to be a long. See the Integer Constants page for details.

Syntax

long var = val;

Parameter Values

  • var: variable name.
  • val: the value assigned to the variable.

Example Code

long speedOfLight_km_s = 300000L; // see the Integer Constants page for explanation of the 'L'
