Unfortunately, I keep seeing people who claim to be old hands at floating point 
making these unlearned remarks. I have no issue with neophytes like the OP 
expecting different results and asking questions. It is those who answer them 
with an air of authority that need to take a greater responsibility for knowing 
what they are talking about. I lament the teachers, not the pupils.
