Well... they all share the "price" dimension, right?
Potentially, yes...
mcs::units allows arbitrary (or nearly so) unit conversions at runtime, but is restricted to a static set of fundamental units (whatever they may be).
Like I feared.
Just to clarify, the set of fundamental units is defined at compile time, but is not mandated by the library. That is, you could define apples oranges flops 1970s USD tribbles as the set of fundamental units and the library would happily perform compile-time dimensional analysis on integer or fractional powers of combinations of these units...
So you think mcs::units cannot possibly support run-time currencies in the near and far future?
If you're willing to do runtime conversions within the value_type (as I discussed in a previous post on currency conversion), then mcs::units could support arbitrary runtime conversion of currencies relatively easily.
