ios - 如何在 Swift 中找出 Int 的最大值

Question

我想了解如何访问 Int 的“struct”类型。当我用 cmd 单击 Int 时，它把我带到了这个类，我想找出它可以容纳的最大值是多少。有没有办法从其中一个属性中提取？这个结构中的最大值和最小值是多少？

struct Int : SignedInteger {
    var value: Builtin.Word
    init()
    init(_ v: Builtin.Word)
    init(_ value: Int)
    static func convertFromIntegerLiteral(value: Int) -> Int
    typealias ArrayBoundType = Int
    func getArrayBoundValue() -> Int
    static var max: Int { get }
    static var min: Int { get }
}

Answer 1

“You can access the minimum and maximum values of each integer type with its min and max properties:

let minValue = UInt8.min  // minValue is equal to 0, and is of type UInt8
let maxValue = UInt8.max  // maxValue is equal to 255, and is of type UInt8

The values of these properties are of the appropriate-sized number type (such as UInt8 in the example above) and can therefore be used in expressions alongside other values of the same type.”
