Function GeodesicInverseResult.finalAzimuth

Forward azimuth at the endpoint, canonicalized from -pi inclusive to +pi exclusive.

Angle!T finalAzimuth() const pure nothrow @nogc @property @safe;

This is not the back azimuth.

Example

Example reading the final forward azimuth. 

import geodesy;
const solver = Geodesic!double.fromEllipsoid(wgs84!double());
const start = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(48.20849),
    Longitude!double.fromDegrees(16.37208));
const end = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(47.07071),
    Longitude!double.fromDegrees(15.43950));
const result = solver.inverse(start, end);
assert(result.finalAzimuth.radians == result.finalAzimuth.radians);
}
