Hi. I would like to convert an Int to an hex string. I found the String.toInt(radix:Int) but didn’t find the opposite.

[konsoletyper]

println("FF".toInt(16))

[konsoletyper]

Ah, sorry, now I see

[konsoletyper]

fun Int.toString(radix: Int) = asDynamic().toString(radix)

[konsoletyper]

println((255).toString(16))

@gaetan @konsoletyper But it wont work for negative values, (-12).toString(16) will return -c not FF...F4

[konsoletyper]

You can easily work-around this

[konsoletyper]

For example, (-12 and 0xFF).toString(16). Note that Kotlin JVM has the same behaviour

[bamdmux]

@konsoletyper Yeah, I know thats a JVM problem, just was warning him

[bamdmux]

And that will print F4, (-12).and(0xFFFFFFFF).toString(16) will return -c

[bamdmux]

@gaetan If you want to work with hexadecimal representations, your best option will be using List<Byte> and then converting byte to byte byte.toInt().and(0xFF).toString(16)

[gaetan]

Thanks for the proposal. In fact, it’s just to convert a color from an Int to its hex string representation.

The @konsoletyper solution do the job.
