Units users,

How do I define an operator* which takes a quantity<length>,quantity<length> and returns a quantity<area>? This doesn't seem to be defined in the boost::units, which somewhat surprises me. How do we make something like that part of the core definition?

My mistake. I was multiplying quantity<length> * quantity<length> * float (effectively), which doesn't work. Instead my PI value needs to be captures by a dimensionless, then it works like a charm.

Thanks,

Michael
