From firmware versions V3.01 and above there is an option to allow numbers to be rounded. The reason for
this is driven primarily from a control point-of-view. With truncation, it is quite likely that the PV will look as though
it never settles onto setpoint. The rounding/truncation affects the UI display and MODBUS scaled integers, the
underlying numbers are not affected, nor the values saved in the history files. Over MODBUS comms, all
floating point parameters that are read via scaled integer comms will take note of the configured setting for
rounding or truncating and reflect this. On the UI, ALL floating point values rendered will adhere to the
configured setting of rounding or truncating.
