Random tidbits

Jamin: Here’s some google juice for
you. ;-)

Got yet another solution to the floating point problem, this one from
Ingo Luetkebohle. He pointed out the existence of DBL_MANT_DIG and
frexp(), so one can simply check whether the difference in exponents
is greater than the number of digits in the mantissa. While it’s not
as short a solution as using the volatile keyword, this is still a
cool solution and I’m sure it can come in handy for a variety of other
situations. :-)
