Rollup Analysis of Booleans

I would like to be able to do a Rollup Analysis of Booleans attributes, without casting or converting the boolean. As Rollup Functions I would suggest: Logical AND, Logical OR and maybe Count of True/False. It can be use to create a Combined Status or a Master Alarm of several Units.

    Would you only have True/False as your possible states?

    In computer science, the Boolean data type is a data type that has one of two possible values (usually denoted true and false) https://en.wikipedia.org/wiki/Boolean_data_type

    A Rollup of digital status could also be nice, but I think much much more complex then rolling-up Booleans

    I was also hoping for this functionality. Could the Maximum and Minimum functions be extended to allow AF's standard Boolean data type? (1=True, 0=False) Maximum would enable OR functionality directly and both would allow the user kludgy AND and NOR functions. I have kludged around this by setting Boolean data as an Enumeration Set and storing to an Integer tag, then using the Maximum function to create a Combined Status/Master Alarm.
