In Java, a power function is used to calculate the result of raising a number (base) to a specific exponent (power). This can be done using the built-in method Math.pow(double base, double exponent), which returns the base raised to the power of the exponent. The method accepts two double values as arguments and returns the result as a double. For example, Math.pow(2, 3) will return 8.0, as 2 raised to the power of 3 equals 8. While this method handles positive and negative exponents, it’s important to note that it may not work for very large or very small numbers due to floating-point precision limits.
