I was worried that doing so would open a hornets nest where people would want a full set of Excel-like stats functions: modes, medians, etc (which I think should be a plugin). Meanwhile, averaging makes quite a good example of a more complex calculation, and demonstrates that more complex operations can be built from the primitives provided. But having said that I’m open to arguments… Best wishes Jeremy > > Best > Diego > > On Thursday, February 7, 2019 at 6:06:59 PM UTC-6, TonyM wrote: > Jeremy, > > So to be clear, you believe, using the triple curly braces will be sufficient > to place calculated values anywhere we want? > > Note that there's nothing specific about the maths operators; they are used > just the same as the other filter operators.
