The function is called numeric_value as it returns the numeric value of the
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)
