I have the feeling I am overlooking something terribly obvious and perhaps someone can point out what obvious place I have left my glasses.

I have a number in an N-ary property with a number.  Plain output (?<property># -) does not give me numbers without commas.  If I feed the number into an expr: with a comma, then it complains about it.  I can strip the comma with a #replace, or I can produce comma less numbers by bogusly declaring the number as a Date.

Help:custom units describes creating custom datatypes, but it's not clear to me from the docs I can use this to remove the commas.

Does anyone have a tidier solution to the goal of getting a value that can be numerically range searched but does not format it in a way that makes #expr complain?
