Number formatting in Scala?

Question

I have a dynamically changing input reading from a file. The numbers are either Int or Double. Why does Scala print .0 after every D

Answer 1

Use type inference, rather than explicit typing.

scala> val xi = 1
xi: Int = 1

scala> val xd = 1.0
xd: Double = 1.0

scala> println(xi)
1

scala> println(xd)
1.0
