/**
* Available since 1.2.0.
*
* ZINCRBY key increment member
*
* 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.
*
* **There is no compliment ZDECRBY. Us a negative increment for that**
*
* **Return value**<br>
* Bulk string reply: the new score of member (a double precision floating point number),
* represented as string.
