Just a question: why is the member called numeric_value? are there other values?
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. See for example (in http://physics.nist.gov/cuu/pdf/sp811.pdf) Page v, Checklist for reviewing manuscripts: item (7) "It is clear to which unit symbol a numerical value belongs ... etc" item (10) "There is a space between the numerical value and the unit .. etc" etc. regards Andy Little
