是否存在会同时产生商和提醒的除法运算? [英] Is there a division operation that produces both quotient and reminder?

问题描述

目前，我编写了一些丑陋的代码，例如

Currently I write some ugly code like

    def div(dividend: Int, divisor: Int) = {
        val q = dividend / divisor
        val mod = dividend % divisor
        (q, mod)
    } 

是在标准库中指定的吗?

Is it specified in standard library?

推荐答案

否(如其他答案中所述，BigInt除外)，但是您可以添加它:

No (except for BigInt, as mentioned in other answers), but you can add it:

implicit class QuotRem[T: Integral](x: T) {
  def /%(y: T) = (x / y, x % y)
}

将适用于所有整数类型.您可以通过为每种类型创建单独的类(例如

will work for all integral types. You can improve performance by making separate classes for each type such as

implicit class QuotRemInt(x: Int) extends AnyVal {
  def /%(y: Int) = (x / y, x % y)
}
