Thanks for the link it was helpful. I tried both methods and they both
compiled. It seems we can use the simpler form of decltype because it
provides perfect forwarding. Is this a correct interpretation?
Neither of these two typedef seems to behave as I expected. When creating
a quantity with these typedefs I had to call them as a method to get the
code to compile.
quantitysi::velocity a(2.3 * nautical_miles_per_hour1());
quantitysi::velocity b(2.4 * nautical_miles_per_hour2());
quantitysi::velocity c(2.5 * si::meters_per_second);
Is there a way to get my type of nautical_miles_per_hour to behave like
meters_per_second?
