Hello! This code is not compiling:

Copy code

var b : Byte = 10.toByte()
b += 10.toByte()

Complains about type mismatch: Required Byte got Int. Why?

Copy code

operator fun Byte.plus(other: Byte): Int

Bytes are designed for storage, so that you can have a lot of bytes in memory. They are not designed for doing arithmetics (that’s what

Int

and

Long

are for). So, do you arithmetics in Ints, then coerce and store to bytes if needed.
