Using SCANF with DOUBLE precision variables...

Well, go ahead! K&R, page 149 gives the key to reading in double precision
number using the scanf family:
	"the conversion characters e or f may be preceeded by l (letter l)
	 to indicate that .. a pointer to double rather than float is
	 expected"
The code would look like

double foo;

	scanf("%lf",&foo);

After having my code bomb several times (unfortunately, I was not as lucky
as you - instead of zeroes, I got core dumps), I discovered this little
gem in K&R.
