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 framework (ie toInt())

To convert boolean to integer, let us first declare a variable of boolean primitive. boolean bool = true; Now, to convert it to integer, let us now take an integer variable and return a value “1” for “true” and “0” for “false”. int val = (bool) ?
Use int for casting a Boolean value in Python. Using int() method will convert Boolean to Int, 1 for True and 0 for False.
We convert a Number to Boolean by using the JavaScript Boolean() method. A JavaScript boolean results in one of the two values i.e true or false. However, if one wants to convert a variable that stores integer “0” or “1” into Boolean Value i.e “true” or “false”.
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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
