在Swift中将Int转换为Double

label.text = String(format:"%.1f hour", theOrder.bookingMins/60.0)

The above code just get the error:'Int' is not convertible to 'Double'

上面的代码得到的错误是:'Int'不能转换为'Double'

bookingMins is of type Int, so how do I convert an Int to a Double in Swift? Seems not as simple as in C.

bookingMins是Int类型的，那么如何在Swift中将Int转换为Double呢?似乎没有C语言那么简单。

2 个解决方案

#1

Try Double(theOrder.bookingMins)

尝试双(theOrder.bookingMins)

#2

label.text = String(format:"%.1f hour", Double(theOrder.bookingMins) /60.0)
