Answer 1

hi there trunc function is appropiate because in round and ceil function return
rounded value that is 99.99
ie
SELECT ROUND(99.9899,2) FROM dual;
99.99
SELECT ceil(99.9899) FROM dual;
100
SELECT floor(99.9899) FROM dual;
99but the trunc
Returns n truncated to m decimal places, where m and n are numeric arguments. If m is omitted, truncates to 0 places. If m is negative, truncates (makes zero) m digits to the left of the decimal point.
select trunc(99.9899,2) from dual;
99.98regards
