Prism Central - VM RAM configured in GiB, but isn't actually gibibytes?

**[edit]** Subject should read "Prism **ELEMENT**", not Central. Brain fart. (We don't run *Central* because our cluster is too tiny / don't want to burn the resources for Central, and don't really "need" it for our tiny environment.)

Currently running AOS 6.10.1.6. (I know this is EOS soon and I plan on moving to a newer release in the next month or two).

Prism ~~Central~~ Element says that RAM is configured in GiB - I take this to mean "binary gigabytes" AKA gibibytes.

For example, I have a Linux VM set for "4 GiB" in TCS, but the amount of memory shown in the VM is not 4 GiB.

# free -h total used free shared buff/cache available Mem: 3.7Gi 1.2Gi 280Mi 106Mi 2.6Gi 2.5Gi

Or in bytes:

free -b total used free shared buff/cache available Mem: 4005748736 1306664960 305504256 111857664 2810085376 2699083776

4GiB should be 4,294,967,296 bytes, not 4,005,748,736...
