Scala - Math pow() Method



The Scala Math pow() method returns the base raise to the power of exponent. In special cases it returns the following:

  • If the exponent is zero, then the result is 1.0.
  • If the exponent is NaN, then the result is NaN.
  • If the base is NaN and the exponent is nonzero, then the result is NaN.
  • If the exponent is 1.0, then the result is the same as the base.

Syntax

def pow(base: Double, exponent: Double): Double = 
                   java.lang.Math.pow(base, exponent)

Parameters

base Specify the base.
exponent Specify the exponent.

Return Value

Returns the base raise to the power of exponent.

Exception

NA.

Example:

In the example below, pow() method is used to calculate the base raised to the power of exponent.

import scala.math._

object MainObject {
  def main(args: Array[String]) {
    println(s"pow(10, 2) = ${pow(10, 2)}");  
    println(s"pow(5.2, 3) = ${pow(5.2, 3)}");
    println(s"pow(5.2, -3) = ${pow(5.2, -3)}");
    println(s"pow(5, Double.NaN) = ${pow(5, Double.NaN)}"); 
    println(s"pow(Double.NaN, 2) = ${pow(Double.NaN, 2)}");
    println("pow(2, Double.PositiveInfinity) = "
            + pow(2, Double.PositiveInfinity));
    println("pow(2, Double.NegativeInfinity) = "
            + pow(2, Double.NegativeInfinity));            
  }
}

The output of the above code will be:

pow(10, 2) = 100.0
pow(5.2, 3) = 140.608
pow(5.2, -3) = 0.007111970869367318
pow(5, Double.NaN) = NaN
pow(Double.NaN, 2) = NaN
pow(2, Double.PositiveInfinity) = Infinity
pow(2, Double.NegativeInfinity) = 0.0
