So was I - looks_like_number is doing most of the work already, having it tally up the digits into an UV as it goes makes a lot of sense to me. It is less clear that we want the hassle of the NV case. (Getting the round-decimal-to-binary correct is a pain in the non-integer case - somewhere at work I have some papers on the "right" way to do it that I got last time I was involved in writing C libraries.) >And sv_2[iun]v only calls strtod if looks_like_number thinks >that something looks like its idea of a number, which for integers is >/^\s*[-+]?[0-9]+\s*$/ (if I have my regexp correct, but the important >bit is no commas, (and hardcoded '0' to '9' instead of \d (and a fanatical >loyalty to the Pope)) > >So I think that this means that sv_2[iun]v don't currently "do" locales. >So roll-ones-own just for them doesn't need to either. > >but I think wait until HP UX and Irix are happy before doing more. > >Nicholas Clark -- Nick Ing-SimmonsThread Previous | Thread Next
