Detailed Description

template<class TYPE, typename Gaudi::Math::TypeWrapper< TYPE >::value_type I, unsigned int N1, unsigned int N2>
struct Gaudi::Math::IDigits< TYPE, I, N1, N2 >

Simple structr efor compile-time evaluation of the range of decimal digits N1->N2 (N2 is excluded) for the given integral type.

  const int dig02 = IDigits<unsigned int,4362736,0,2>::value ;

Attention:

the least significant decimal digit is numbered as #0
