exp()

Calculates the value of Euler's number e (2.71828...) raised to the power of a number.

Examples

exp example 1

function setup()
  size(100, 100)

  background(200)

  -- Top-left.
  local d = exp(1)
  circle(10, 10, d)

  -- Left-center.
  d = exp(2)
  circle(20, 20, d)

  -- Right-center.
  d = exp(3)
  circle(40, 40, d)

  -- Bottom-right.
  d = exp(4)
  circle(80, 80, d)

  describe('A series of circles that grow exponentially from top left to bottom right.')
end

exp example 2

function setup() 
  size(100, 100)

  background(200)

  describe('A series of black dots that grow exponentially from left to right.')
end

function draw() 
  -- Invert the y-axis.
  scale(1, -1);
  translate(0, -100)

  -- Calculate the coordinates.
  local x = frameCount;
  local y = 0.005 * exp(x * 0.1)

  -- Draw a point.
  point(x, y)
end
