Bearing
On this page
A compass direction: degrees clockwise from true north, from 0 to 360.
Use it for which way something is heading. geo.bearing gives one between two points. For an angle that isn't a direction, use Angle.
Shape
One Decimal from 0 to 360.
Example
Bearing(247.5)A value outside its limits breaks min or max.
text.parse(raw, as: Bearing) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 90°, N or 1.5rad.
This operation gives one: geo.bearing.
Good to know
text.formatshows247.5°.==tells you whether two are the same, and<andlist.sort_bycompare and sort them.
In JSON
A string, in a request, a response or json.write:
"0""90""247.5"
Details
Text form, storage, how it is shown, and operations
Bearing is in the group Geospatial, and has been in Jadpo since 0.1.0.
Text form
text.from writes one standard text form, the same form text.parse reads back: 0, 90 and 247.5.
How it is stored
It is stored in one column named for the field, of type numeric. 247.5 is stored as 247.5.
How it is shown to people
text.format(value, locale:) shows it to people in their locale.
With locale: Locale.en_gb:
| Value | Shown |
|---|---|

0° |
90 |

Operations
geo.bearing(from: Point, to: Point) -> Bearing: The direction the geodesic leavesfromin, in degrees clockwise from true north, at least 0 and below 360, to 9 places. Two equal points have none: the call fails withsame_point, which itsattemptmaps.
It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
