I want to have the integer value of the following floating point value:
我想要具有以下浮点值的整数值：
var floatingPointValue = NSDate().timeIntervalSince1970 * 1000
I don't care if the integer value of this floating point number is actually an integer or a string.
我不在乎这个浮点数的整数值实际上是整数还是字符串。

Int64 is large enough to hold a time interval of some million years measured in milliseconds:
Int64足够大，可以以毫秒为单位保持几百万年的时间间隔：
let milliSeconds = Int64(someDate.timeIntervalSince1970 * 1000)
let milliSecondsString = String(milliSeconds)

Int64 is enough to hold the value you needed
Int64足以保存您需要的值
let floatingPointValue = NSDate().timeIntervalSince1970 * 1000
let intValue = Int64(floatingPointValue)
