Hi,

I am using BOOST to do math and have not been able to get the "findroot_demo.cpp" example of root finding to work. There seem to be a reference to rint(), which is not implemented in the C++ library for windows. How can I solve this - my understanding of BOOST is that it is cross-platform?

Thanks in advance.
