Numeric Type Conversion: Integer and Floating-Point Conversion 

Let three = 3
let pointOneFourOneFiveNine = 0.14159
let pi = Double(three) + pointOneFourOneFiveNine
// pi equals 3.14159, and is inferred to be of type Double
Let integerPi = Int(pi)
// integerPi equals 3, and is inferred to be of type Int
