* feat(region-routing): P1 tagging + region_routes primitive + read/write API + preview launcher - config.py: add Coverage.region_tagging (bool=False); add RegionRouteMatrix dataclass (enabled, cells) above NotificationsConfig; add region_routes field to NotificationsConfig; add explicit hydration branch for region_routes in _dict_to_dataclass mirroring destinations pattern. - coverage_area.py: add MonitoringArea.name (str|None=None, frozen); update areas_from_config to preserve name; refactor inline geom extraction from classify_event_areas into shared _event_geom_json helper; add matching_area_names(geom_json, areas)->list[str] (additive, all named matches, config-order, deduped; gate unchanged); add event_region_names convenience wrapper. - coverage_filter.py: add region_tagging ctor kwarg; stamp event.region/ regions before the gate when region_tagging=True and areas non-empty and not event.regions (never clobbers satpass preset). - pipeline/__init__.py: wire region_tagging into CoverageFilter construction. - notification_routes.py: add GET /notifications/regions (named coverage area names, config-order, deduped); GET /notifications/region-routing (matrix as JSON); POST /notifications/region-routing (explicit RMW — only region_routes changes, toggles/rules/destinations survive). - scripts/preview_dashboard.py: mesh-free launcher — dashboard API only, no mesh connector, no broadcast loop; vite runs separately. All 87 coverage tests pass; 300 total pass; 6 pre-existing failures unchanged (adapter config count mismatch + MeshCore EventType.NEW_CONTACT). * feat(region-routing): manual region x family matrix editor page Adds RegionRoutingMatrix.tsx — a plain editor over the region_routes config primitive. Rows = families (via useFamilies()), cols = regions (from GET /api/notifications/regions). Each cell exposes MT channel (ChannelPicker single + includeDisabled), MC channel name (text input), min_severity select (routine/priority/critical/immediate), and an enabled checkbox. Only cells where MT or MC is set are included in the sparse POST payload. Master enable toggle maps to top-level enabled. MT budget guard warns when more than 7 distinct MT indices are in use. Sticky family column; horizontal scroll for wide region sets. Registers route /region-routing in App.tsx and adds "Region Routing" nav entry (Map icon) under the Meshtastic section in Layout.tsx, immediately after Routing.

3.4 KiB
The light version of decimal.js, an arbitrary-precision Decimal type for JavaScript.
This library is the newest of the family of libraries: bignumber.js, big.js, decimal.js and decimal.js-light.
The API is more or less a subset of the API of decimal.js.
Differences between this library and decimal.js
Size of decimal.js minified: 32.1 KB.
Size of decimal.js-light minified: 12.7 KB.
This library does not include NaN, Infinity or -0 as legitimate values, or work with values in other bases.
Here, the Decimal.round property is just the default rounding mode for toDecimalPlaces, toExponential, toFixed, toPrecision and toSignificantDigits. It does not apply to arithmetic operations, which are simply truncated at the required precision.
If rounding is required just apply it explicitly, for example
x = new Decimal(2);
y = new Decimal(3);
// decimal.js
x.dividedBy(y).toString(); // '0.66666666666666666667'
// decimal.js-light
x.dividedBy(y).toString(); // '0.66666666666666666666'
x.dividedBy(y).toDecimalPlaces(19).toString(); // '0.6666666666666666667'
The naturalExponential, naturalLogarithm, logarithm, and toPower methods in this library have by default a limited precision of around 100 digits. This limit can be increased at runtime using the LN10 (the natural logarithm of ten) configuration object property.
For example, if a maximum precision of 400 digits is required for these operations use
// 415 digits
Decimal.set({
LN10: '2.302585092994045684017991454684364207601101488628772976033327900967572609677352480235997205089598298341967784042286248633409525465082806756666287369098781689482907208325554680843799894826233198528393505308965377732628846163366222287698219886746543667474404243274365155048934314939391479619404400222105101714174800368808401264708068556774321622835522011480466371565912137345074785694768346361679210180644507064800027'
});
Also, in this library the e property of a Decimal is the base 10000000 exponent, not the base 10 exponent as in decimal.js.
Use the exponent method to get the base 10 exponent.
Quickstart
Browser:
<script src='path/to/decimal.js-light'></script>
Node package manager:
$ npm install --save decimal.js-light
// Node.js
var Decimal = require('decimal.js-light');
// Adjust the global configuration if required (these are the defaults)
Decimal.set({
precision: 20,
rounding: Decimal.ROUND_HALF_UP,
toExpNeg: -7,
toExpPos: 21
});
phi = new Decimal('1.61803398874989484820458683436563811772030917980576');
phi.toFixed(10); // '1.6180339887'
phi.times(2).minus(1).toPower(2).plus('1e-19').equals(5); // true
