DECRBY key decrement

Decrements the number stored at key by decrement. If the key does not exist, it is set to 0 before performing the operation. An error is returned if the key contains a value of the wrong type or contains a string that can not be represented as integer. This operation is limited to 64 bit signed integers.

See INCR for extra information on increment/decrement operations.
