hincrby with decimals

[Benjamin Polidore]

I'm using the 2.2.111-scripting tag, and I can't do HINCRBY with a decimal.  For example:

redis 127.0.0.1:6379> hget account:h50 usd

"100"

redis 127.0.0.1:6379> HINCRBY account:h50 usd 22.01

(error) ERR value is not an integer or out of range

I'm pretty sure i used to be able to do this with the main branch.  Why not allow incrementing by a decimal?

This hasn't been possible since at most 1.3.10 (I tried it then, found
it didn't work, and used zsets instead).

The INCR family uses 64-bit integers range. If you know what the
precision is you need up front, you can choose to store a multiple so
you don't need to work with floats. In the case of USD, you would be
storing cents instead.

Cheers,
Pieter

Ok that makes sense. I can do that no problem. I guess my unit test
was flawed when I was using the main branch.
