Describe the Feature Request

Add a new kind of Attribute to support Float

Describe the Use Case

Be able to store float type of number

Example 1: a device is 7,7 kg, I would like to be able to set 7,7 kg and not be force to either set 8 kg or 770 gr
Example 2: a device is 1.5 U of height, I would like to be able to have to put 2U. (on a 48U rack it's 32 devices instead of 24)

We are using Number internally in a few places but it would probably make most sense to change all those instances to Integer instead, remove Number and create a new Float. Number doesn't really tell us anything about about the actual type.
