Perform a mathematical operation on a variable with another constant or variable. The += (et al) operators are just a convenient shorthand for the expanded syntax below.

Syntax

x+=2;   // equivalent to the expression x = x + 2;
x-=2;   // equivalent to the expression x = x - 1; 
x*=2;   // equivalent to the expression x = x * 2; 
x/=2;   // equivalent to the expression x = x / 2;

Parameters

x: any variable type

Examples

x = 2;
x++;      // x now contains 3
x--;      // x contains 2 again
