Anyone reading this who hasn't been to the mat with actual numerical calculations on a computer really needs to know that getting it right is HARD and there are a million ways to do the obvious thing but get the wrong answer. One of the great things about FORTRAN was that the math libraries were *very* sophisticated and tried to save the uninitiated from their own stupidity; and I speak as one whose stupidity triumphed over them and once calculated a spectacularly wrong result which got placed on the desk of a senior executive and had to be apologized for; I still shudder thinking of it. -- Cheers, Tim Bray (ongoing fragmented essay: http://www.tbray.org/ongoing/)
