Use Saint Andreas Math for mathematical operations:
Here are some common examples of mathematical computing, which shows how to use functions and methods in the Saint Andreas Math class library for mathematical calculations.
1. Calculate the square root:
import com.saintandreas.math.MathUtils;
public class MathExample {
public static void main(String[] args) {
double number = 16;
double squareRoot = MathUtils.sqrt(number);
System.out.println ("square root:" + squareroot);
}
}
2. Calculate absolute value:
import com.saintandreas.math.MathUtils;
public class MathExample {
public static void main(String[] args) {
double number = -10;
double absoluteValue = MathUtils.abs(number);
System.out.println ("absolute value:" + absolutevalue);
}
}
3. Calculate the number:
import com.saintandreas.math.MathUtils;
public class MathExample {
public static void main(String[] args) {
double number = 100;
double logarithm = MathUtils.log(number);
System.out.println ("Dive:" + Logarithm);
}
}
4. Generate random numbers:
import com.saintandreas.math.RandomUtils;
public class MathExample {
public static void main(String[] args) {
int min = 1;
int max = 100;
int randomNumber = RandomUtils.getRandomInt(min, max);
System.out.println ("Random Number:" + Randomnumber);
}
}
