cpotting, amazing story. You might find this amusing: A mathematician, an engineer and an accountant were asked What is 2+2?
never underestimate the ability of accountants to ignore facts and plod on anyway ("Numbers be d***ned - the amounts don't matter, just as long as they balance!").
Mathematician replied 4
Engineer replied 4.000 plus or minus 0.001
Accountant replied - What to you want it to be?
