#Instance methods ##Iteration

times

• times <T> (call: () -> T)
• times (call: () -> ())

Iterates call, self times.

• times <T> (call: (Int) -> T)

Iterates call, with an Int index argument, self times.

Example

5.times { println("Hi") }
/* Prints → */
// → Hi
// → Hi
// → Hi
// → Hi
// → Hi

---

upTo

• upTo (limit: Int, call: (Int) -> ())

Iterates call, passing in integer values from self up to and including limit.

Example

5.upTo(7, { println($0) })
/* Prints → */
// → 5
// → 6
// → 7

---

downTo

• downTo (limit: Int, call: (Int) -> ())

Iterates call, passing in integer values from self down to and including limit.

Example

7.downTo(5, { println($0) })
/* Prints → */
// → 7
// → 6
// → 5

##Math

isEven

• isEven () -> Bool

Returns true if self is even.

Example

4.isEven()
// → true

isOdd

• isOdd () -> Bool

Returns true if self is odd.

Example

3.isOdd()
// → true

clamp

• clamp (range: Range<Int>) -> Int
• clamp (min: Int, max: Int) -> Int

Computes the value of self clamped to a range defined by range (or min...max).

Example

5.clamp(0...4)
// → 4

1.clamp(2...4)
// → 2
