About the V Format Element in Oracle

When using the TO_CHAR() function to format a number in Oracle Database, you can use the V format element to a return a value multiplied by 10(and if necessary, round it up), where n is the number of 9s after the V.

Examples

Here’s an example to demonstrate:

SELECT TO_CHAR(1, '9V9') FROM DUAL;

Result:

10

Here are some more examples:

SELECT 
    TO_CHAR(1, '9V99') AS "99",
    TO_CHAR(1, '9V999') AS "999",
    TO_CHAR(1, '9V9999') AS "9999",
    TO_CHAR(1, '9V99999') AS "99999",
    TO_CHAR(74, '99V999999') AS "999999"
FROM DUAL;

Result:

     99      999      9999      99999       999999 
_______ ________ _________ __________ ____________ 
 100     1000     10000     100000     74000000   

Here are some examples that use fractions:

SELECT 
    TO_CHAR(1.23, '9V99') AS "r1",
    TO_CHAR(0.23, '9V99') AS "r2",
    TO_CHAR(-0.23, '9V99') AS "r3",
    TO_CHAR(74.8934, '99V999999') AS "r4"
FROM DUAL;

Result:

     r1      r2      r3           r4 
_______ _______ _______ ____________ 
 123      23     -23     74893400    

We can use the fm modifier to suppress any padding, such as leading/trailing spaces:

SELECT 
    TO_CHAR(1.23, 'fm9V99') AS "r1",
    TO_CHAR(0.23, 'fm9V99') AS "r2",
    TO_CHAR(-0.23, 'fm9V99') AS "r3",
    TO_CHAR(74.8934, 'fm99V999999') AS "r4"
FROM DUAL;

Result:

    r1    r2     r3          r4 
______ _____ ______ ___________ 
123    23    -23    74893400    

Rounding

Rounding occurs if necessary:

SELECT 
    TO_CHAR(1.1152, '9V99')
FROM DUAL;

Result:

112
