There's an arbitrary rule that you round up for .5, according to my third 
grade teacher. =) I just mentioned that in case it's something someone cares 
about. It doesn't bother me because I've never encountered a practical 
situation where it mattered.

However, I've always assumed the reason for the rule was that the original 
number might have been truncated from something higher than the .5 value, 
like .53. I suppose this *could* be a practical consideration if your input 
is from a user who might have truncated the number.
