Hi, Section 8 of Lists 3 has an algorithm to "generate a counter representation". Step 2 says to use the absolute value for the rest of the algorithm, but this is not what we want. For example, with the 'repeating' type, we want the values -1 and -2 to be represented by the last and second-to-last symbols, respectively (assuming two or more symbols). Using the absolute value would result in using the first and second symbols. The "absolute value" part of step 2 should be removed and the algorithm for some type adapted: * repeating: the modulo on negative dividends must be consistent with the above * numeric: take the absolute value before the rest of the algorithm * other types: unchanged. While we’re at it, it would be good to replace every occurrence of "positive" and "negative" (for integer values) by either "strictly positive/negative" or "positive/negative or zero". PS: I write about various issues as I find them. Would it be better (less spam-ish for the list or easier for editors) to aggregate them and send a single email every now and then?
