Just to correct and extend my example a bit.
The sign() return 0 if argument are equal with 0
SELECT
DECODE( sign( a - 15 ), -- Tested value
-1 , 'Less than 15', -- Compaired value and the retun value if match
0 , 'Equal to 15
'Grater than 15' ) -- Default value if no earlier match (Can be omitted)
FROM DUAL;
