Hi, from the MySQL 4.1 manual: --- The DECIMAL and NUMERIC data types are used to store exact numeric data values. In MySQL, NUMERIC is implemented as DECIMAL. These types are used to store values for which it is important to preserve exact precision, for example with monetary data. --- and there is lot more there at http://dev.mysql.com/doc/refman/4.1/en/numeric-types.html , check it out, hope it helped.
