Six months in and I’ve finally worked out how to show rain to 1 d.p. for mm and 2 d.p. for inches, with trailing zeros. I’ve left rain rate/hour showing 2 d.p. for both. (This release can’t show rain rate/min without more work, and I’m not really interested anyway.)
Small YTD-MTD rainfall block has a temporary “real-estate” solution: for both mm and inches, if ($amount<100) show 2 d.p.; for (100<$amount<1000) show 1 d.p.; ($amount>1000) show 0 d.p. Seems like a workable balance?
