Struct Angle

A finite angle stored canonically in radians.

struct Angle(T)
  
if (isGeodesyScalar!T);

.init represents zero radians. Construction accepts float, double, or real; checked factories reject non-finite input without throwing, while throwing factories report the same failure with GeodesyValueException.

No allocation is performed by checked construction or value access.

Properties

NameTypeDescription
degrees[get] TAngle value converted to degrees.
radians[get] TAngle value in canonical radians.

Methods

NameDescription
fromDegrees (degrees) Construct from degrees.
fromRadians (radians) Construct from radians.
tryFromDegrees (degrees, result) Construct from degrees without throwing.
tryFromRadians (radians, result) Construct from radians without throwing.

Example

Example using an angle with checked and throwing construction. 

import geodesy;

const quarterTurn = Angle!double.fromDegrees(90.0);
assert(quarterTurn.degrees == 90.0);

Angle!double checked;
assert(Angle!double.tryFromRadians(0.5, checked));
assert(!Angle!double.tryFromRadians(double.nan, checked));
