In Java, a power function is used to calculate the result of raising a number to a specific power. Java does not have a direct operator for exponentiation, but the Math.pow() method in the java.lang package provides this functionality. The method takes two arguments: the base and the exponent, both of type double.
Example:
java
double result = Math.pow(2, 3); // 2 raised to the power of 3 = 8.0
The result is always returned as a double, even if the inputs are integers. This function is widely used in mathematical computations, scientific calculations, and algorithms requiring exponential operations.
