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

var x:Double = 1
var y:Double = 1.0

print(x) // => 1.0
print(y) // => 1.0

If i understand you question you want scala to print x and y differently? The problem is that x and y are both a variable of the type Double and look the same.

Why do you explicitly define the type of the vars?

var x = 1 
var y= 1.0

print(x) // => 1
print(y) // => 1.0
