Is there an easy way to convert a Boolean to an Integer?

I am new to Scala and I am finding the need to convert a Boolean value to an Integer. I know I can use something like if (x) 1 else 0 but I would like to know if there is a preferred method, or something built into the language (i.e. toInt()).

Solution

  • If you want to mix Boolean and Int operation use an implicit as above but without creating a class:

    implicit def bool2int(b:Boolean) = if (b) 1 else 0

scala> false:Int
res4: Int = 0

scala> true:Int
res5: Int = 1

scala> val b=true
b: Boolean = true


scala> 2*b+1
res2: Int = 3
