And now...just a wee reminder that it is possible for the chip makers to 
build errors into their floating point processors.  Even large, 
well-known chip makers whose names start with "Intel."  

And it's possible for software writers to write bugs into their floating 
point software routines.  Even large companies deeply involved in the 
IEEE standards process and producing an excellent implementation of that 
standard...including one whose name starts with "Apple" (whose code in 
rare cases messed up the low bit of the mantissa).

So...while the issue you raised isn't the result of an error, that 
doesn't mean that no strange result is ever an error.  Keep questioning 
oddities!  Understanding flows therefrom.
