fun <C : Comparable<C>> C.coerceAtMost(maxValue: C) = if (this > maxValue) maxValue else this
fun <C : Comparable<C>> C.coerceAtLeast(minValue: C) = if (this < minValue) minValue else this
fun <C : Comparable<C>> C.coerceIn(minValue: C, maxValue: C) = coerceAtLeast(minValue).coerceAtMost(maxValue)

Also

fun <C : Comparable<C>> min(vararg elements: C): C
fun <C : Comparable<C>> max(vararg elements: C): C

I'm a bit surprised these methods aren't part of stdlib of any languages i know of. Is there a reason I haven't considered?

They are available. The only difference is that `min`/`max` functions are defined as extensions on iterables and arrays. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.ranges/coerce-at-most.html https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.ranges/coerce-at-least.html https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.ranges/coerce-in.html https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/min.html https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/max.html

i don't understand how i somehow missed it when i'm running 1.4-M3 and it's been in since 1.3 maybe i wasn't using comparable classes on accident... idk
