I'm trying to figure out how to check to see if the year is evenly divisible by 4. I'm not sure how to see if 'v_result' is a whole number.
ACCEPT p_leapyear PROMPT 'Please enter a year: '
DECLARE
v_leapyear NUMBER(4) := &p_leapyear;
v_result NUMBER(4);
BEGIN
v_result := v_leapyear / 4;
IF v_result ????? THEN
DBMS_OUTPUT.PUT_LINE (v_leapyear||' is a leap year.');
ELSE
DBMS_OUTPUT.PUT_LINE (v_leapyear||' is not a leap year.');
END IF;
END;
I tried converting it to_char(v_result,'9999'), to_char(v_result,'9999.99') and using date format fmYYYY, but so far no luck.

Remember that dividing by 4 is only one of the leap year checks. A more robust solution would use the built-in Oracle date datatype to tell if a year was a leap year or not.
declare
v_year integer;
v_date date;
begin
v_year := 2002;
v_date := to_date('02/29/' || v_year, 'mm/dd/yyyy');
dbms_output.put_line(v_year || ' is a leap year');
exception
when others then
dbms_output.put_line(v_year || ' is NOT a leap year');
end; |
