Discussion
Use the half-open range operator (..<) to create a range of any type that conforms to the Comparable protocol. This example creates a Range<Double> from zero up to, but not including, 5.0.
let lessThanFive = 0.0..<5.0
print(lessThanFive.contains(3.14)) // Prints "true"
print(lessThanFive.contains(5.0)) // Prints "false"
