RE: How Accurate is Accurate Enough?

A topic I have seen is "the most accurate calculator" or other similar themes, with 10, 12, 14, or even more digits accuracy. It makes me ask, how accurate is accurate enough? I worked on guided missiles with nothing more FORTRAN double precision numbers (about 16 digits) My involvement with the missile program came to an end when I goofed and forgot a comma changing a line of code like this DO 100 I=1,500 to this DO 100 I=1 500 according to FORTRAN, the second line assigns 1500 to the variable DO100I instead of looping and incrementing the variable I 500 times. Both statements are perfectly legal in FORTRAN IV which ignores imbedded spaces. The missile had to be aborted. The brass weren't amused. Tom L Cui bono? |
