Clamp

Clamp is a library with the single purpse of providing clamp() and clamped() functions to Swift's built-in integer and floating point types. The clamp() and clamped() functions limit a value to the inclusive range of the passed-in minimum and maximum values.

Usage

// immutable version
5.clamped(lowerBound: 1, upperBound: 10) // returns 5
0.clamped(lowerBound: 1, upperBound: 10) // returns 1
11.clamped(lowerBound: 1, upperBound: 10) // returns 10

5.clamped(to: 1...10) // returns 5
0.clamped(to: 1...10) // returns 1
11.clamped(to: 1...10) // returns 10

// mutable version
var number = 5
number.clamp(to: 1...10) // no change
number.clamp(to: 1...4) // `number` is changed to 4
number.clamp(to: 10...20) // `number` is changed to 10
