6893	Inaccurate Radians/Degrees conversion	pieterb@…	Jürgen Hunold	"LS,

The conversion from angles in degrees to radians currently uses a conversion factor of  6.28318530718/360. (File: boost\units\base_units\angle\degree.hpp), which equals 0.0174532925199444444...

This is unnecessarily inaccurate (only 14 significant digits are correct) and gives problems in my application - the actual value reads: 0.017453292519943295769236907684886127134428718885417...

Using this value improves conversion accuracy significantly.

Please consider using this more accurate value. Alternatively, the use of boost::math::constants could be considered, making the factor:
boost::math::constants::pi<double>()/180.0
which works fine as well.
