1.1) =
|
||
*Time complexity O(log(N)) with N being the number of elements in the sorted set*
|
||
If *member* already exists in the sorted set adds the *increment*
|
||
to its scoreand 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 asorted set value an error is
|
||
returned.
|
||
|
||
The score value can be the string representation of a double
|
||
precision floatingpoint number. It's possible to provide a negative
|
||
value to perform a decrement.
