Unable to set_disk_free_limit mem_relative to 1.0 or higher

[bdshroyer]

When rabbitmqctl set_disk_free_limit mem_relative is invoked with a value of 1.0 or higher, you get the following error message:

Error: {{function_clause,
            [{rabbit_resource_monitor_misc,parse_information_unit,
                 [{mem_relative,1.0}],

Looks like this was introduced in 829890b, and is a misunderstanding of what the value is.
