PLSQL | REMAINDER Function

The REMAINDER function is an inbuilt function in PLSQL which is used to return the remainder of a divided by b. Syntax:

REMAINDER(a, b)

Parameters Used: This function accepts two parameters a and b which is used in calculating the remainder when a is divided by b. Return Value: This function returns a numeric value when the input number a is divided by b. Supported Versions of Oracle/PLSQL is given below:

1. Oracle 12c
2. Oracle 11g
3. Oracle 10g
4. Oracle 9i
5. Oracle 8i

Let's see some examples which illustrate the REMAINDER function: Example-1:

DECLARE 
   Test_Number number1 := 15;
   Test_Number number2 := 5;
   
BEGIN 
   dbms_output.put_line(REMAINDER(Test_Number number1, 
                                  Test_Number number2)); 
   
END; 

Output:

0

In the above example, when 15 is divided by 5 then it returns a remainder of 0. Example-2:

DECLARE 
   Test_Number number1 := 11.6;
   Test_Number number2 := 2;
   
BEGIN 
   dbms_output.put_line(REMAINDER(Test_Number number1, 
                                  Test_Number number2)); 
   
END; 

Output:

-0.4

In the above example, when 11.6 is divided by 2 then it returns a remainder of -0.4 Example-3:

DECLARE 
   Test_Number number1 := -15;
   Test_Number number2 := 4;
   
BEGIN 
   dbms_output.put_line(REMAINDER(Test_Number number1, 
                                  Test_Number number2)); 
   
END; 

Output:

1

In the above example, when -15 is divided by 4 then it returns a remainder of 1. Advantage: This function is used to find out the remainder when a is divided by b.
