yes (except perhaps on very old equipment that had a sign bit and not 
2s-complement), but that does not stop people from expecting that
floor(-x+.5)==-floor(x+.5) everywhere.
I was talking about expectations not definitions. (ok, 'would' in stead 
of 'should' would (should?) have been better)

no it doesn't, that was the whole point. In some cases people want a 
function that round halves away from zero. round(-3.5)=-4
