[boost] How to cast _1 ?

I want to cast a value of _1 to a _val of a different type. How do I do
that? I tried using static_cast_, it does not compile for me.

rule<UInt8Iterator, UInt32()> MyRule;

...

MyRule = (long_ | float_)                                         [_val =
static_cast_<UInt32>(_1)]

Any help is appreciated

Regards,

Henry
