In the Stdlib the companion of

Byte

looks like this:

public class Byte private constructor() : Number(), Comparable<Byte> {
    companion object {
        public const val MIN_VALUE: Byte = -128
        public const val MAX_VALUE: Byte = 127
...

Double

on the other hand looks like this:

public class Double private constructor() : Number(), Comparable<Double> {
    companion object {
        public val MIN_VALUE: Double
        public val MAX_VALUE: Double
...

Is there are a particular reason, why the properties in

Double

are not

const

? This prevents me to use those properties in my own constants.

Seems non trivial to find a valid kotlin double expression that is the max value

@spand Why? 1.7976931348623157E308 is a valid Kotlin expression

Didn’t equal max value when I tried but maybe I made a mistake

That's weird, this is what println(Double.MAX_VALUE) gave me

Not at a computer but should be easy to check :-)
