+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.
+
+@return
+
+@bulk-string-reply: the new score of `member` (a double precision floating point
+number), represented as string.
