i can't be the only one that thinks the constant casting between ints, doubles, etc in arithmetic kinda ruins the beautiful readability of kotlin

Have an example of when it's ugly in arithmetic?

how about a^2 + b^2 = c^2:

fun Pair<Int,Int>.distanceTo(to: Pair<Int,Int>): Float = sqrt((this.first - to.first).toDouble().pow(2.0) + (this.second - to.second).toDouble().pow(2.0)).toFloat()

So in that example, you could add a

pow

extension function to

Int

right and avoid all the conversion calls? Or are ya looking for a lib that has already defined many extensions like that on numeric types?
