Re: [Boost-users] [mpl::math] exponential metafunction for complex types

Thanks, that works great. I also noticed that there is a problem with the double exponential metafunction. For example: #include #include #include <iostream> int main() { typedef boost::mpl::math::zero_dispatchboost::mpl::math::double_tag double_zero; typedef boost::mpl::math::string_c_to_double<'-',2,'.',0>::type minus_two; typedef boost::mpl::timesboost::mpl::math::double_tag

::type minus_two_pi;

std::cout << boost::mpl::math::exponential::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 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].
