DECIMAL

A packed decimal number. The length is specified as two integers separated by a comma. The first integer is the precision of the number (the total number of digits), which can range from 1 to 31. The second integer is the scale of the number (the number of digits to the right of the decimal point), which can range from 0 to the precision. If you specify precision, but not scale, the default for scale is 0. If you leave length blank, the default for precision is 5 and the default for scale is 0.
