We often wonder and write all the codes to display negative numbers in brackets. But this can be easily achieved using a TO_CHAR function with the correct format.
TO_CHAR(number, '9999PR') -
Returns negative value in angle brackets.
Returns positive value with a leading and trailing blank.
Restriction: The PR format element can appear only in the last position of a number format model.
Below is an example to achieve this
select to_char(-133133,'99999999999PR') from dual
In above example the number is displayed in brackets without comma seperator.
Following query can be used to display negative numbers in angular bracket with comma seperator.
select to_char(-133133,'999G999G990D99PR') from dual
