After on-lining some new systems that have 2 TB of memory our statistics page started receiving errors.

Oops, we're sorry but something went wrong
x Unknown string: "1.97 TB"!
If you feel this is an error with Foreman itself, please open a new issue with Foreman ticketing system, You would probably need to attach the Full trace and relevant log entries.

This is with version 0.4

We were able to workaround this issue by editting lib/core_extensions.rb:
