Expire doesn't seem to work with non-integer arguments for seconds

[akshitdewan]

Hi,

I ran the following code:

await client
        .multi()
        .zadd(key, score, member)
        .expire(key, 50.555)

And when the expiration key is a floating point value like 50.555, the TTL seems to remain -1. Is this intended behavior? Is it possible to enforce an integer requirement or choose a different default?
