fun DoubleArray.min(): Double(source)

Returns the smallest element.

If any of elements is NaN, this function returns NaN.

Since Kotlin

1.7

Throws

NoSuchElementException

if the array is empty.

@JvmName(name = "minOrThrow")

fun <T : Comparable<T>> Array<out T>.min(): T(source)

Returns the smallest element.

If there are multiple equal minimal elements, this function returns the first of those elements.
