11 * Some silly typedefs to make our units very explicit.
13 * Also, the units are chosen so that values can be expressible as
14 * integers, so that we never have FP rounding issues. And they
15 * are small enough that converting to/from imperial units doesn't
18 * We also strive to make '0' a meaningless number saying "not
19 * initialized", since many values are things that may not have
20 * been reported (eg cylinder pressure or temperature from dive
21 * computers that don't support them). But sometimes -1 is an even
22 * more explicit way of saying "not there".
24 * Thus "millibar" for pressure, for example, or "millikelvin" for
25 * temperatures. Doing temperatures in celsius or fahrenheit would
26 * make for loss of precision when converting from one to the other,
27 * and using millikelvin is SI-like but also means that a temperature
28 * of '0' is clearly just a missing temperature or cylinder pressure.
30 * Also strive to use units that can not possibly be mistaken for a
31 * valid value in a "normal" system without conversion. If the max
32 * depth of a dive is '20000', you probably didn't convert from mm on
33 * output, or if the max depth gets reported as "0.2ft" it was either
34 * a really boring dive, or there was some missing input conversion,
35 * and a 60-ft dive got recorded as 60mm.
37 * Doing these as "structs containing value" means that we always
38 * have to explicitly write out those units in order to get at the
39 * actual value. So there is hopefully little fear of using a value
40 * in millikelvin as Fahrenheit by mistake.
42 * We don't actually use these all yet, so maybe they'll change, but
43 * I made a number of types as guidelines.
