struct

Geode::Angle

Inherits Comparable < Struct < Value < Object

The Angle struct represents a geometric angle. Basic arithmetic as well as trigonometric functions can be applied to it.

Constructors

new(measure : Number::Primitive, unit : Symbol = :radians)

Creates a new Angle.

Source

Instance methods

*(other : Number)

Multiplies an angle's measure by the given scalar.

Source

+(other : Angle)

Adds the measures of two angles.

Source

-(other : Angle)

Subtracts the measure of one angle from another angle.

Source

/(other : Number)

Divides an angle's measure by the given scalar.

Source

<=>(other : Angle)

Compares the measures of two angles.

Source

boundary?

Returns whether or not the given angle lines on a quadrant boundary, i.e. whether the angle's measure is divisible by 1/2pi / 90 degrees.

Source

cos

Returns the cosine function of the angle.

Source

cot

Returns the cotangent function (inverse tangent) of the angle.

Source

csc

Returns the cosecant function (inverse sine) of the angle.

Source

degrees

Returns the angle's measure in degrees.

Source

full?

Returns whether or not the given angle represents a full circle, i.e. whether the angle's measure is divisible by 2pi / 360 degrees.

Source

half?

Returns whether or not the given angle represents a semi-circle, i.e. whether the angle's measure is divisible by pi / 180 degrees.

Source

normalize

Returns a new Angle with the measure restricted to the interval [0, 2pi) / [0, 360).

Source

quadrant

Returns which quadrant the angle lies in. If the angle lies on a quadrant boundary, it returns nil.

Source

radians

Returns the angle's measure in radians.

Source

reference

Returns the reference angle, i.e. the smallest angle that the terminal side makes with the x-axis.

Source

sec

Returns the secant function (inverse cosine) of the angle.

Source

sin

Returns the sine function of the angle.

Source

tan

Returns the tangent function of the angle.

Source

to_point(distance : Number = 1, center : Point = Point.new)

Returns the Point that lies distance units away from the terminal side centered at center.
