dart-angles

Never ever suffix your angle variables with ...degress or ...rad and forget about manual angle conversions like x * rad2deg!

This library provides a single class named Angle, wrapping your angle variables in a far more readable way, whereas raw doubles aren't very expressive about how they store their values. One can create an angle from various units, including degrees, radians, gradians and turns.


// Various ways to define a half turn:
x = Angle.fromDegrees(180.0);
y = Angle.fromRadians(math.pi);
z = Angle.fromTurns(0.5);

x.degrees; // = 180.0
x.radians; // = 3.1415...
x.turns;   // = 0.5

One can use built-in trigonometric functions:


x = Angle.asin(0.3);
y = x.sin; // = 0.3

Angles are immutable, but there are operators like +, creating new angles:


x = Angle.halfTurn() + Angle.fromDegrees(90.0);

example/angles_example.dart

import 'package:angles/angles.dart';
import 'dart:math' as math;

main() {
  // Various ways to define a half turn:
  final x = Angle.fromDegrees(180.0);
  final y = Angle.fromRadians(math.pi);
  final z = Angle.fromTurns(0.5);
  
  x.degrees; // = 180.0
  x.radians; // = 3.1415...
  x.turns;   // = 0.5

  // One can use built-in trigonometric functions:
  final a = Angle.asin(0.3);
  print(a.sin); // = 0.3
  
  // Angles are immutable, but there are operators like +, creating new angles:
  final threeQuarterTurn = Angle.halfTurn() + Angle.fromDegrees(90.0);
  print(threeQuarterTurn); // 270°
}
