The term decrement stands for incremental reduction. The decrement is the amount by which an existing digit
is to be reduced. If the decrement is 2 and the digit is 8, the result of decrementing is 6. The opposite is the increment
, which increases a number by the value of the increment. Decrementing decreases the initial value by the decrement in steps. This technique is used in looping programs when counting down individual program steps. Many programming languages have a decrement command.
