Can someone please show me the accepted inputs/formatting for the numerical tolerance value field in BC?

Also, is it required that a "key" be set? I don't have any keys other than three sets of numerical values that have to be within 250/1000 of each other.

Thanks in advance and my search didn't provide any answers so sorry in advance if this has already been asked.

Love BC!
