The pow() function calculates the value of the
Figure 1 shows the mathematical representation of the pow() function.
The following module is required for this function:
import scala.math._
Double pow(Double baseNumber, Double exponent)
The pow() function requires two parameters:
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.
