Hi Saif,
Would this work?
import scala.collection.JavaConversions._
new java.math.BigDecimal(5) match { case x: java.math.BigDecimal =>
x.doubleValue }
It gives me on the scala console.
res9: Double = 5.0
Assuming you had a stream of BigDecimals, you could just call map on it.
myBigDecimals.map(_.doubleValue)
to get your Seq of Doubles. You will need the JavaConversions._ import to
allow Java Doubles to be treated by Scala as Scala Doubles.
