In the Units library, the default value type is (currently) double and the semantics of all arithmetic operations are based on this built-in type. No assumptions are made about semantics, only that the required operations exist for ValueType. What is the default value type in Quan? I'm guessing it has something to do with a united value or some other manipulation of value semantics within Quan? Also be careful of literal values and promotions. 3 is an integer, 3.0 is a double, 3L is a long, 3LL is a long long, etc. Eric.
