Re: [boost] [ublas] bug with boost::rational types

When using uBlas objects with boost::rational types, the program fails to
compile throwing this error (MS Visual Studio 2003, SP1)

 

c:\boost_1_34_0_beta\boost_1_34_0\boost\numeric\ublas\traits.hpp(89): error
C2665: 'abs' : none of the 5 overloads can convert parameter 1 from type
'const ratio'

 

This code shows the bug:

 

      typedef boost::rational<int> ratio;

 

      vector<ratio> r(2);

      r[0] = ratio(2,3);

      r[1] = ratio(2,7);

 

      ratio dNorm = index_norm_inf(r);    <-- Error Line

 

Any suggestion to fix it?

 

Thanks,
