The decrement operator is a special case of subtraction, and subtracts the a number from a variable. This cannot be used on literals or constants. This operator is a single instruction by itself and can only affect one variable at a time.

FDS Edit

Example Edit

Spike got one less.
Icon Warning There was one less cider.
I would Icon Warning subtract Spike Icon Warning from cider.

This subtracts 1 from the variable Spike and then from cider, and then subtracts Spike from cider.

Its Java equivalent is as follows:

cider -= Spike;
