I'm sorry, but the first thing you should do, before posting a message to=20
a mailing list, is to think "have I researched enough? will I make myself=20
look stupid if I post this question?"

As it turns out, you did not do your homework. Googling=20
for "std::numeric_limits" yields the APIDOX for libstdc++:
http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/structstd_1_1numeric=
__limits.html

If you click "min", you get the following description:
The minimum finite value, or for floating types with denormalization, the=20
minimum positive normalized value.

So there's your explanation: std::numeric_limits<double>::min() is the=20
minimum positive value.
