Sebastian Limbach b9e29f7cbe Moved Scalar_factor_traits specialization for Sqrt_extension number type from Algebraic_foundations package to the Sqrt_extension-SFT file in the Number_types package. 2007-09-03 13:45:21 +00:00
Sylvain Pion a0f9754bbe Add radius(Interval_nt). 
Replace compare_relative_precision() by has_smaller_relative_precision()
