Maths Functions in Java

Maths Functions in Java are define within Math class. The most of math functions are static functions that’s why used always will Math class as Math.method();.

Output Value

round()

This function rounds off the decimal post digits of the given fractional number. It will work as suppose there is one digit after decimal in fractional number and if it is 5 or greater than 5 then it will be treat as 10 otherwise 0, and so on for two ,three…. digits after decimal position.

Syntax

Math.round (fractional number);

Syntax of round()

Example

Input Value

public class mathsm {
    public static void main(String[] args)   
    {  
    
        double y = 12.36;    
        System.out.println(Math.round(y));      

    }  
}

round()

Output Value

abs()

this function returns the positive value of the given negative value but vice-versa not true.

Syntax

public static int abs(int i)  
public static double abs(double d)  
public static float abs(float f)  
public static long abs(long lng)  

Syntax of abs()

Example

Input Value

public class mathsm {
    public static void main(String[] args)   
    {  
    
        float x = -23.5f;       
        long y = 255525; 
        double z = 258.3674;  
        int r = 12;
      
        System.out.println(Math.abs(x));  
        System.out.println(Math.abs(y));
