if member already exists in the sorted set adds the increment to its score and updates the position of the element in the sorted set accordingly . if member does not already exist in the sorted set it is added with increment as score ( that is , like if the previous score was virtually zero ) . if key does not exist a new sorted set with the specified member as sole member is crated . if the key exists but does not hold a sorted set value an error is returned . < p > the score value can be the string representation of a double precision floating point number . it ' s possible to provide a negative value to perform a decrement . < p > for an introduction to sorted sets check the introduction to redis data types page . < p > time complexity o ( log ( n ) ) with n being the number of elements in the sorted set
