Greetings physics enthusiasts,

To all those wise-ass dumb-fscks who adamantly claim that a knowledge
of floating point operations is superfluous, this one is for youse (you all).

You, and a lab down the hall, are both investigating a new algorithm
for simulating an important phenomenon.  You both have identical
machines and systems and are both compiling the software with GCC
(but any compiler will behave the same).

You are compiling with the fast-math option, because you are a wise-ass
dumb-fsck and you believe that only computational speed is important.
The lab down the hall is using options for IEEE754 compliance.

You are experiencing a lot of divide-by-zero exceptions and other strange
problems that is halting progress.  The lab down the hall is doing very
well with no issues.

Someone suggests to contact F. Russell, the world renowned authority, for
his advice.  F. Russell, however, tells you all to go and pound sand because
he does not accept wise-ass dumb-fscks as clients.  (You can file an
anti-discrimination suit but wise-ass dumb-fscks are not protected.)

So what do you do?  What is the source of the problem and how do you
fix it?

You all got big fat mouths, so use 'em.

Ha, ha, ha, ha, ha, ha!  There ain't no one gonna get the EASY EASY EASY
solution!

Note: the fictitious scenario depicted above is not all outlandish
or far-fetched and does represent a possibly very common occurrence.
