INTEGER- Integer number
NUMBER- The storage of both fixed and floating point number by using the format
NUMBER(precision, scale), where precision is the total number of digits and scale is the number of digits to right of decimal point. For the example of “amount number(5,2)”, 123.46 is valid, and 12345 is invalid. REAL- Real number
SMALLINT- Short integer
