Java Math


Java Tutorial » Java Math

Java Math class contains methods to perform basic numeric operations as: elementary exponential, square root, logarithm, and trigonometric functions.

Java supply several methods to work with math calculations as: min(), max(), avg(), cos() ,sin() tan(), ceil(), round(), abs(), floor() etc.

 


Java Math class, example


Example:
public class Main {
public static void main(String[] args) {
double a = 36;
double b = 9;

System.out.println("a = 36,");
System.out.println("b = 9,");

// max(a,b) method - find the highest value of a and b:
System.out.println("1. Highest number between a and b is: " +Math.max(a, b));

// return the square root of a
System.out.println("2. Square root of a is: " + Math.sqrt(a));

//returns 36 power of 9 = 36*36*36*36*36*36*36*36*36
System.out.println("3. Power of a and b is: " + Math.pow(a, b));

// return the logarithm of given value
System.out.println("4. Logarithm of a is: " + Math.log(a));
System.out.println("4.1 Logarithm of b is: " + Math.log(b));

// return a power of 2
System.out.println("5. exp of a is: " +Math.exp(a));

// random number between 0 and 998
int randomNum = (int)(Math.random() * 998);
System.out.println("6. Random number between 0 and 998 is: " +randomNum);
}
}
Output:
a = 36,
b = 9,
1. Highest number between a and b is: 36.0
2. Square root of a is: 6.0
3. Power of a and b is: 1.01559956668416E14
4. Logarithm of a is: 3.58351893845611
4.1 Logarithm of b is: 2.1972245773362196
5. exp of a is: 4.311231547115195E15
6. Random number between 0 and 998 is: 728
