使用swift

Question

所以想象一下，我希望我的代码在0.25中计算，我希望它像：0.00,0.25,0.50 ...但它目前是：0,0.25,0.5 ......   我的代码中的那部分是这样的：

if (Score >= 0 && Score < 10.00){
    Score += 0.25
    HighScoreLabel.text = "The Score is \(Score)"
}

Answer 1

let score = 0.5
let stringDisplay = String(format: "%.02f", score)
println("The Score is \(stringDisplay)")   // "The Score is 0.50"

String Format Specifiers
