- Rational, yes, though a transcendental bent helps to see it that way.
-
- Expressing an angle as a fraction of a circle has a number of computational
- advantages. Conversion amongst radians for math, DMS for maps & people, and
- grads for arty are simple & straightforwrd. Additionally, the properly
- signed minor arc difference between two angles can be computed in 5
- instructions, from load to store.
-
- Scaling is not a problem, as the binary point is always after the sign bit.
