degrees()

Converts an angle measured in radians to its value in degrees.

Degrees and radians are both units for measuring angles. There are 360˚ in one full rotation. A full rotation is 2 × π (about 6.28) radians.

The same angle can be expressed in with either unit. For example, 90° is a quarter of a full rotation. The same angle is 2 × π ÷ 4 (about 1.57) radians.

Examples

degrees example 1

function setup() 
  size(100, 100)
  fill(0)
  background(200)

  -- Calculate the angle conversion.
  local rad = QUARTER_PI
  local deg = degrees(rad)

  -- Display the conversion.
  text(round(rad, 2)..'rad = '..deg..'˚', 10, 50)

  describe('The text "0.79 rad = 45˚".')
end

Syntax

degrees(radians)

Parameters

Parameter
radians Number: radians value to convert to degrees.

Returns

Number: of the angle
