Hi,

I wanted to use the boost::numeric::interval<T> types for simple arithmetic
and elementary functions. I expected them to work out of the box (at least
for T=double). However, only arithmetic (+,-,*,/) works. I get name look up
errors when I try something like sin(..) or cos(..) of an Interval type.

The example with the compiler errors are here: http://codepad.org/4LmWiHiS

I tried grepping my global include directory for what the compiler reported
it couldn't find (cos_up, cos_down) and the only place it seems to be
defined in is:

[00:57][~]$ grep -iRl cos_up /usr/include/
/usr/include/boost/numeric/interval/transc.hpp

And, including that file doesn't seem to help at all as you can see in the
paste.

Also on a related note, *none* of the examples here:
https://gforge.inria.fr/scm/viewvc.php?view=rev&root=std-interval&sortby=date&revision=5would
compile. I expected at least the examples to work out of the box but
they don't.

Thanks,
Chillu
