浮點到整數轉換Swift

Question

我想將浮點值轉換為int。 例如，我的浮點值是40.22，我需要像這樣的int值4022。

 let price : String  = valueArray.objectAtIndex(5) as! String
 let floatValue : Int = Int(price)! * 100

Answer 1

您可以這樣嘗試：

var myInt = Int(40.22*100)

要么

var myInt = Int(price*100)

Answer 2

這是最好的解決方案，

let price : Float = 40.22

let stringValue : String = "\(price)"

print(stringValue)     //This prints "40.22"

let intString = stringValue.stringByReplacingOccurrencesOfString(".", withString: "")

print(intString)       //This prints "4022"

if let intValue = Int(intString) {
    print(intValue)    //This gives 4022
}

Answer 3

您可以嘗試此解決方案，我希望一切順利。

let price : String  = "40.4534522"
let myStringArr = price.componentsSeparatedByString(".")
let finalString = myStringArr[0] + myStringArr[1]
let requiredInt = Int(finalString)
print(requiredInt!)
