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
