Re: [Boost-users] A question on switch_statement. Can any one with kindness help me?

Oh,I made a mistake.value is a double.And I need to round it to int . And I still want to know whether I can use make_const(switchvalue) or constant(switchvalue) instead of switchvalue? Even var(switchvalue)? in : int result,switchvalue; .............. (switch_statement(_1, case_statement<1> (var(result)=0), case_statement<2> (var(result)=1), case_statement<3> (var(result)=constant(value)), default_statement (var(std::cout)<<"wrong") ))(switchvalue);
