For example, the predicate shown in the first expression is internally converted in the second expression.Ī filter argument overrides the existing corresponding filters over the same column(s), unless it is embedded within KEEPFILTERS. When a filter argument has the form of a predicate with a single column reference, the expression is embedded into a FILTER expression that filters all the values of the referenced column. RemarksĮvery filter argument can be either a filter removal (such as ALL, ALLEXCEPT, ALLNOBLANKROW), a filter restore ( ALLSELECTED), or a table expression returning a list of values for one or more columns or for an entire expanded table. (I mean, how do you break it to Rajveer Meena, a world-record holder, that he just recited 70,000 digits of one half of the true circle constant?) Since the circle constant is important, it’s important to get it right, and we have seen in this manifesto that the right number is \( \tau \).The value is the result of the expression evaluated in a modified filter context. It’s precisely because it does matter that it’s hard to admit that the present convention is wrong. I care enough to write a whole manifesto, and you care enough to read it. People care enough about it to write entire books on the subject, to celebrate it on a particular day each year, and to memorize tens of thousands of its digits.
