Kotlin max()

In Kotlin, the max() function is used to return the greater of two given values provided as arguments. It can be used with numeric types such as Double, Float, Int, Long, UInt, and ULong. Both values must be of the same type.

Note: The max() function is different from the maxOf() function that can take one or more than two arguments. If max() is used with more or less than two arguments the program will raise an error.

Syntax

import kotlin.math.*

val greatestVal = max(x, y)

• Where x and y represent two numeric values of the same type.

Example

The following example shows the usage of max() comparing two Long values:

import kotlin.math.*

fun main() {
    val longValue1: Long = 9223372036854775807L
    val longValue2: Long = 9222372036854775807L

    val greatestValue = max(longValue1, longValue2)
    println("The greater value is: $greatestValue")
}

• In the above example, longValue1 and longValue2 are both of type Long. The L at the end of the numbers is optional and indicates that these are long literals.
