- stared 7y agoI think you missed the point. Units != dimensions. E.g. angle in radians, degrees and full rotations differs by a factor. It is a typical, and common, mistake that would benefit from such system.
- quantified 7y agoAll numeric concepts that have any meaning whatsoever have units/“dimensions”. Probability is in units of possible outcomes. If your chances are affected non-linearly, you’d express that (chance of death per inch of penetration). No percentages are unitless. If they were, you could substitute them without consequence, like applying an interest rate percentage in place of a mortality rate pecentage or an alcohol-to-water percentage. Angles, exponents, counts all fit in units, just more complex unit expressions.
- touisteur 7y agoIsn't the idea to mix types and dimensionality analysis? With mathematics libraries in a language like Ada your angles will usually be one type, your distances another, and the rate of change another, and so on.
