INCRBY

INCRBY key increment

Available since 1.0.0.

Time complexity: O(1)

Increments the number stored at key by increment. 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-

Return value

Integer reply: the value of key after the increment

Examples

redis> SET mykey "10" "OK" redis> INCRBY mykey 5 (integer) 15
