,
Increments the number stored at field
in the hash stored at key
by
increment
.
If key
does not exist, a new key holding a hash is created.
If field
does not exist the value is set to 0
before the operation is
performed.
The range of values supported by HINCRBY
is limited to 64 bit signed integers.
Examples
Since the increment
argument is signed, both increment and decrement
operations can be performed:
