Scala - error: recursive variable name needs type

Question

I'm using an older version of scala 2.7.5

When i try to do computations like this,

var x = 100

var x = x%1000

I get a

error: recursive variable x needs type

Is there a work around? why do i get this error?

Answer 1

You're declaring the variable twice rather than just changing its value. Instead, do

var x = 100
x = x%1000
