The function is called numeric_value as it returns the numeric value of the quantity.
quan::length::mi my_journey(25); // distance in miles quan::length_<int>::nm dx (25); // distance in nanometers
The numeric value of journey is 25, the numeric value of dx is 25, but the units are very different.
What you are getting with the call to 'numeric_value' is the scalar component of the "quantity" - right? Just a suggestion then, would a more reasonable name for the method be 'magnitude'; it sounds better, and ties better to the problem domain.
