Kotlin - Make extension function accessible in whole project

Question

I have this extension function in a class:

fun Double.round2() : Double {
   return Math.round((this) * 100.0) / 100.0
}

I want to reuse this function in another class without the need to duplicate the code. How can I do it? Thank you.

Your function should be defined at the top level. It will be automatically visible anywhere from the same package, and from other packages with the help of an import statement.

Thank you. I think this is a problem, cause you you always have to organize your project taking in account this limitation. – Migue Quintanilla Dec 04 '18 at 14:47

Which limitation? There are no limitations involved here, just additional features which you should embrace. – Marko Topolnik Dec 04 '18 at 19:59
