---
Returns the number of elements in the sorted set at `key` with a score between
`min` and `max`.

The `min` and `max` arguments have the same semantic as described for
[`ZRANGEBYSCORE`]({{< relref "/commands/zrangebyscore" >}}).

Note: the command has a complexity of just O(log(N)) because it uses elements ranks (see [`ZRANK`]({{< relref "/commands/zrank" >}})) to get an idea of the range. Because of this there is no need to do a work proportional to the size of the range.

## Examples

{{% redis-cli %}}
ZADD myzset 1 "one"
ZADD myzset 2 "two"
ZADD myzset 3 "three"
ZCOUNT myzset -inf +inf
ZCOUNT myzset (1 3
{{% /redis-cli %}}
