[Or did I miss a design document} It would give the warm fuzzy illusion that I could always add another layer at 1.0000000025 between 1.000000002 and 1.000000003 but in practice surely there will be a nasty surprise as the implementation dependant limit on floating point accuracy bites and two levels that I thought were different were actually the same. And what happens if I set precedences of -0, Inf or NaN? [Or failing that whatever HUGE_VAL evaluates to?] Nicholas ClarkThread Previous | Thread Next
