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);
