#7 Mathematical Operators in java

Mathematical Operators

As we saw in the preceding example there are particular symbols used to represent operators when performing calculations:

Styling Tables

Opeerator	Description	Example – given a is 15 and b is 6
+	Addition	a + b, would return 21
-	Subtraction	a - b, would return 9
*	Multiplication	a * b, would return 90
/	Division	a / b, would return 2
%	Modulus	a % b, would return 3 (the remainder)

class Example4

{ 

public static void main(String args[]) 

{

 int iresult, irem;

 double dresult, drem; 

iresult = 10 / 3; 

irem = 10 % 3;

 dresult = 10.0 / 3.0; 

drem = 10.0 % 3.0; 

System.out.println("Result and remainder of 10 / 3: " + iresult + " " + irem); System.out.println("Result and remainder of 10.0 / 3.0: " + dresult + " " + drem);

 }

 }

Predicted Output:

 Result and Remainder of 10/3: 3 1 

Result and Remainder of 10.0/3.0: 3.3333333333333335 1

The difference in range is due to the data type since ‘double’ is a double precision 64-bit floating point value.
