let cftB:Double = 72.365
let sRe:String = cftB.description
print("description方法: "+sRe)
let cftC:Double = 11.341
let sK:String = "\(cftC)"
print("結果3: "+sK)
// String()方法を使用
let price:Double = 45.68
let sRes:String = String(price)
print("String()方法: "+sRes)
// description方法を使用
let cftB:Double = 72.365
let sRe:String = cftB.description
print("description方法: "+sRe)
let cftC:Double = 11.341
let sK:String = "\(cftC)"
print("結果3: "+sK)
// String()方法を使用
let price:Double = 45.68
let sRes:String = String(price)
