virtual-machine memory always rounds down

[eric-eisenhart]

NetBox version

v3.3.1

Python version

3.9

Steps to Reproduce

1. Create a virtual-machine
2. Edit memory to a number that isn't an even multiple of 1024, such as "2045", "2560", or "4095"
3. Save and view the virtual-machine

Expected Behavior

Memory should display as a more reasonably rounded number or include a single digit after the decimal.

For 2045MB, any of "2.0 GB" or "2 GB" would be better.

For 4095MB, any of "4.0 GB" or "4 GB" would be better.

For 2560MB, either "2.5 GB" or "3 GB" would be an improvement over "2 GB".

Observed Behavior

A number rounded down by as much as 1023 is displayed:

• 2047 MB = "1 GB"
• 4095 MB = "3 GB"
• 2560 MB = "2 GB"

To avoid any confusion resulting from rounding, we should convey the exact value unless it can be expressed as an exact number of gigabytes or terabytes.
