Thanks, that works great. I also noticed that there is a problem with the double exponential metafunction. For example: #include <boost/mpl/math/double.hpp> #include <boost/mpl/math/complex_number.hpp> #include <iostream> int main() { typedef boost::mpl::math::zero_dispatch<boost::mpl::math::double_tag> double_zero; typedef boost::mpl::math::string_c_to_double<'-',2,'.',0>::type minus_two; typedef boost::mpl::times<minus_two,boost::mpl::math::pi_dispatch<boost::mpl::math::double_tag>
::type minus_two_pi;
std::cout << boost::mpl::math::exponential<minus_two_pi>::type() << std::endl; return 0; } outputs: 0.0788433 I increased BOOST_MPL_LIMIT_MATH_EXPONENTIAL_SERIES to 32, but I am not sure what exactly this should be. the example program outputs: 0.00186744 Chris On 2/21/07, Cromwell Enage <sponage@yahoo.com> wrote:

The problem was in the sine and cosine functions, which by default lose their accuracy when the angle is beyond tha range (-pi/2,pi/2).
Sorry, I meant [-pi,pi].
