The Nature of Functions

Right now I'm trying to decide how to represent units. They will have dimensional orders - such as MLT^-1 (mass x length / time) for units of momentum. Then there must be a function f:R->R (e.g. long double f(long double)) to map each dimension's unit to SI units. For many units, these will simply be scale factors, for a few others they may involve shifts as well - in other words, all these unit conversions are affine transformations.... read more
