Redis Zincrby Command

Redis Sorted Sets (sorted set)

The Redis Zincrby command adds an increment increment to the score of the specified member in the sorted set

You can pass a negative value increment to subtract the corresponding value from the score, such as ZINCRBY key -5 member, is to subtract the score value of member 5 .

If the key does not exist, or the score is not a member of the key, ZINCRBY key increment member is equivalent to ZADD key increment member .

If the key is not a sorted set type, an error is returned.

The score value can be an integer or a double-precision floating-point number.
