Compatibility:: Redis Software and Redis Cloud compatibility

Increments the score of member in the sorted set stored at key by increment. If member does not exist in the sorted set, it is added with increment as its score (as if its previous score was 0.0). If key does not exist, a new sorted set with the specified member as its sole member is created.

An error is returned when key exists but does not hold a sorted set.

The score value should be the string representation of a numeric value, and accepts double precision floating point numbers. It is possible to provide a negative value to decrement the score.

Required arguments

key

The name of the key that holds the sorted set.

increment

The amount to add to the member's current score.

member

The member whose score to increment. It is added with the increment as its score if it does not exist.

Return information
