Angle

class Angle

Data type, represents angle units as they used in CSS.

const sector = 12deg;
const rotation = 2rad;

Angle literals are JS numbers immediately followed by unit charactes.

List of supported units, standard CSS units:

• rad - radians;
• deg - degree;
• grad - gradian, is equivalent to 1⁄400 of a full circle;
• turn - 1turn == 360deg;

90deg is the same as 100grad is the same as 1.508rad.

properties:

• angle.quantity:number

reports number of units in the angle. For 12px it will return 12.

• angle.units:string

reports unit name. For 12px it will return "px".

methods:

• angle.valueOf():number

returns number of radians.

• angle.toString():number

returns string representation.

operators:

Angle units support following operators:

• a * n - multiplication by number;
• a / n - division by number;
• a + b - sum of two lengths;
• a - b - substraction of two lengths;
• a == b - equality of two lengths;
• a < b,a > b, a <= b, a >= b - comparison of two lengths;
• +a - unary plus operator;
• -a - unary minus operator;
• ++a, a++ - increment operator;
• --a, a-- - decrement operator;

static methods:

• Angle.rad(n):angle

• Angle.deg(n):angle

• Angle.grad(n):angle

• Angle.turn(n):angle

  These above are all static constructors of angle values.
