Common math functions.
The Math Class
java.lang.Math is a built-in class of static math methods. It is in java.lang, so no import is needed. You call methods on the class: Math.sqrt(2).
Powers and Roots
Math.pow(base, exp) raises a number to a power, and Math.sqrt(x) takes a square root. Both return double.
public class Main {
public static void main(String[] args) {
System.out.println(Math.pow(2, 10));
System.out.println(Math.sqrt(144));
}
}
