Why ^ is not allowed is Kotlin? How would we calculate 2 ^ 3 in Kotlin?

I found only Double and Float has pow() but not Int. Is it the only way to solve as

2.toDouble().pow(3.toDouble()).toInt()

Need some help

Need some help

we know. thats why you’re posting a question in #C0922A726

the shortest way to write your function would probably be

2.0.pow(3)

with a .toInt() if you need it - but maybe the result would be better represented as a long or a BigInteger, depends on the size of your input, and the compiler can’t account for that

[Shawn]

if you peek into its definition, you’ll find that kotlin.math.pow just delegates to java.lang.Math on the JVM

[Shawn]

and if you google integer power java you get this stackoverflow post https://stackoverflow.com/questions/8071363/calculating-powers-of-integers

In Java we have an equivalent ^ symbol and can calculate 2 ^ 3 easily.

[Shawn]

I’m sorry, what does System.out.println(2 ^ 3); print out on your machine

Perhaps you are referring to the xor operator? Which is just xor in Kotlin.

Oh I was mis interpreting xor as pow. My mistake. Thanks for help.

One more source of confusion in Java that Kotlin clears up!

By making bitwise operations annoyingly verbose.
