Overview

The nextUp() method is a static method in the math package that returns the floating-point number adjacent to the first argument towards the direction of the positive infinity.

Scala internally uses Java implementations of the corresponding methods. This method internally invokes nextUp() method in Java.

Syntax

math.nextUp(x)

Parameters

  • x: The starting floating point or a double number.

Return value

The method returns the nearest floating-point/double number in the direction of positive infinity adjacent to the given number.

Example

import scala.math
object Main extends App {
val x: Double = 43.12
println(s"starting point - ${x}")
val newNum = Math.nextUp(x)
println(s"Number adjacent to ${x} towards positive infinity - ${newNum}")
}
The nextUp() method in Scala

Explanation

  • Line 6: The following value after x in the direction of positive infinity is obtained by invoking the nextUp() method. The value returned is stored in newNum.
  • Line 7: Print the newNum.
