4799,Linker error in math library - rint() missing on MS windows platform,larsvmogensen@…,John Maddock,"I tried solving this through the forum, but it seems to be a bug more than newbe problems.

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?

From what I can see in the source this is also a problem with BOOST 1.44.0 version. I am currently limited to the 1.36.0, but will upgrade if this is solved in the next version. 

Maybe BOOST developers should implement a rint() function for the MS Windows users?
