您可以轻松地将这些值从BigDecimal中舍入为特定精度，也可以同时将其转换为double值. 例如:-

you can easily round up the values into specific precision from BigDecimal , also if you want you can convert it into double value at the same time . For Example : -

scala> val s:BigDecimal = 10.232 s:BigDecimal = 10.232

scala> val s :BigDecimal = 10.232 s: BigDecimal = 10.232

scala> s.setScale(2，BigDecimal.RoundingMode.HALF_UP).toDouble res1:Double = 10.23//转换为Double

scala> s.setScale(2, BigDecimal.RoundingMode.HALF_UP).toDouble res1: Double = 10.23 // CONVERTED AS DOUBLE

scala> s.setScale(2，BigDecimal.RoundingMode.HALF_UP) res2:scala.math.BigDecimal = 10.23//正在路由

scala> s.setScale(2, BigDecimal.RoundingMode.HALF_UP) res2: scala.math.BigDecimal = 10.23 // Rouding Off

因此在scala中，而不是使用math.Round，您可以使用setScale.

So in scala instead of using math.Round you can use setScale.
