API

Create an angle

Create an angle from radians:

radians (2 * pi)

Create an angle from degrees:

degrees 180

Get an angle as a number

Get an angle in radians

getRadians angle

Get an angle in degrees

getDegrees angle

Perform arithmetic operations on angles

Add two angles

angle1 ∠+∠ angle2

Subtract angles

angle1 ∠-∠ angle2

Multiply an angle with a number

angle ∠* n

Divide an angle with a number

angle ∠/ n

Divide two angles (and get a number)

angle1 ∠/∠ angle2

Perform trigonometric operations with angles

sine angle

cosine angle

tangent angle

Inverses gives an angle given a number:

arcsine x

arccosine x

arctangent x

Perform other operations with angles

Normalize an angle to between 0 and 2*pi radians:
