To change a number to a negative number in Kotlin, you can simply multiply the number by -1. For example, if you have a variable num with a value of 5 and you want to make it -5, you can do so by writing num = num * -1. This will change the number to its negative equivalent.

How to utilize Kotlin's built-in functionality to change a number to negative?

You can utilize Kotlin's built-in functionality by using the unaryMinus() operator to change a number to negative. Here's an example code snippet:

val number = 10 val negativeNumber = -number // using unaryMinus() operator

println("Original Number: $number") // Output: 10 println("Negative Number: $negativeNumber") // Output: -10

In this example, the unaryMinus() operator is used to change the number 10 to its negative counterpart -10.

One recommended approach for changing a number to negative in Kotlin is to multiply it by -1. Here is an example:

val number = 5 val negativeNumber = number * -1 println(negativeNumber) // Output: -5

This method is simple and efficient for changing a number to negative in Kotlin.

What is the syntax for changing a number to a negative number in Kotlin?
