swaits	cdab359b4e	enable and fix stricter clippy linting ... - add clippy to .build.yml to run on sr.ht - add missing docs - use core:: instead of std:: where possible - use hypot() and mul_add() for better numeric stability - make all float tests use asser_approx_eq() and explicitly check for NaN/Inf - add missing semicolons here and there - add #[must_use] to ensure caller uses returned value - add const fn where appropriate - change visibility from pub(crate) to pub (in private modules) Signed-off-by: Stephen Waits <steve@waits.net>	2023-02-09 10:54:42 -07:00
swaits	3cf2f27569	test: add property tests to HeightVector ... Which also helped me fix a bug (using is_sign_negative() when we actually are okay with -0.0). Signed-off-by: Stephen Waits <steve@waits.net>	2023-02-07 21:37:21 -07:00
swaits	8f1100d64d	fix: add numeric stability ... Made `HeightVector` numerically safe; while `Vector` remains numerically unsafe (i.e. it can divide by 0, NaN, Inf, etc). When HeightVector runs into a problem, it just re-randomizes itself. Since the algorithm converges relatively quickly, this seems to work fine. Also fixed a bug so that now height will always start as a positive number (and stay that way, else get re-randomized). Added safety to `NetworkCoordinate` which now checks that its error didn’t pull a `HeightVector` into a negative height; in which case it also re-randomizes. Clarified the `random` construction, tweaked the DEFAULT_ERROR constant, and updated tests accordingly. Signed-off-by: Stephen Waits <steve@waits.net>	2023-02-07 20:25:10 -07:00
