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

[hudsonb]

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

[Hullaballoonatic]

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()

[Hullaballoonatic]

the important things to consider in arithmetic are the mathematical operators, but the casting dominates the lines

[Hullaballoonatic]

especially when working with java classes that have the autocasting, so set field types to whatever number type, then in kotlin you have to constantly cast to it

[hudsonb]

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?
