So far, the reduce sub is consistent with all of the examples in his text. User input would accept negative in the minute and second fields (unlike some other calculators), it just won't provide output with negatives in those fields, which are appropriately carried to the next highest term, as is done in this calculator http://www.mathopenref.com/dmscalculator.html

But with the http://www.mathopenref.com/dmscalculator.html calculator, if I enter 0° 0' 59" and then add -0° 1' 0", I get -0° 0' 1". Surely the only way that can happen is if -0° 1' 0" represents a negative angle of 0° 1' 0", i.e., an angle of -1'. (Understandably, the calculator won't let you enter angles like 0° -1' 0" or 0° 0' 60".) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]
