What is Math.pow() in Scala?

The pow() function calculates the value of the numberbase raised to the power of another numberexponent.

Figure 1 shows the mathematical representation of the pow() function.

Syntax

Double pow(Double baseNumber, Double exponent)

Parameters

The pow() function requires two parameters:

A base number
An exponent number

Return value

pow() returns the value of the base number raised to the exponent number.

If the parameter value of the base, exponent, or both is positive infinity, then it returns positive infinity.

If the parameter value of the base, exponent, or both is negative infinity, then it returns zero.

If the parameter value of the base, exponent, or both is NaN, then it returns NaN.

Example

import scala.math._
object Main extends App {
    //positive: baseNumber     positive: exponent
    println(s"The value of pow(2,3) = ${pow(2,3)}"); 
    //positive: baseNumber     negative: exponent
    println(s"The value of pow(0.25,-2) = ${pow(0.25,-2)}"); 
    //negative: baseNumber     positive: exponent
    println(s"The value of pow(-10,2) = ${pow(-10,2)}"); 
    //negative: baseNumber     negative: exponent
    println(s"The value of pow(-0.5,-1) = ${pow(-0.5,-1)}"); 
    //error ouput
    println(s"The value of pow(Double.PositiveInfinity,Double.PositiveInfinity) = ${pow(Double.PositiveInfinity,Double.PositiveInfinity)}");
    println(s"The value of pow(Double.NegativeInfinity,Double.NegativeInfinity) = ${pow(Double.NegativeInfinity,Double.NegativeInfinity)}");
    println(s"The value of pow(Double.NaN,Double.NaN) = ${pow(Double.NaN,Double.NaN)}"); 
}
