|We (software weenies) created a package (wish I could remember the name   |
|of it) that provided basic types LENGTH_UNITS, TIME_UNITS, SPEED_UNITS,   |
|DISTANCE_UNITS, TEMPERATURE_UNITS, ANGLE_UNTIS, etc. and then defined     |
|all of the overloaded operators to convert between those.                 |
|                                                                          |
|[..]                                                                      |
|                                                                          |
|Up side :                                                                 |
|We NEVER had unit conversion issues, as the unit analysis was done by     |
|the compiler.                                                             |
|                                                                          |
|[..]                                                                      |
|mydistance = myspeed * myint ; would not compile.                         |
|                                                                          |
|You can see why the conversion package got so big... it had to defein     |
|ALL valid conversions.                                                    |
|                                                                          |
|Sorry this was so long. Wish I could remember more of the details         |
|It was one of the most fun ADA jobs I worked on.                          |
|                                                                          |
