My biggest issue is that my recent software development experience has involved using Java much more than C++ and I'm trying to learn how to use a C++ library that makes pretty heavy use of templates. Is there a tutorial somewhere that shows examples of doing basic things with this library? The kind of things I'm trying to figure out are: - What is the difference between a "measurement" and a "quantity"? Is it that the former doesn't specify a unit? - Does the library provide functions for converting between different units? ... for example, converting from miles to kilometers. If not, is there a recommended way to do this? - Can I only add quantities that have the same unit or can I add ones with different units and the library will handle conversions for me? - How can I extract the numeric value from a quantity? - How can I extract the unit type from a quantity? Thanks! --- Mark Volkmann
