Real fields accept and contain floating-point numbers, which are useful for displaying very small and very large numbers. You can use real fields to process statistical information in reports.
For real fields, the representation in the database keeps a maximum of ten digits of data. After ten digits, the number is rounded, and the succeeding digits are ignored. For example, if 12345.090009 is entered, the value after a submit is 12345.090010. But if 1234567.090099 is entered, the value after a submit is 1234567.090000. The last three digits are ignored because the rounded answer comes after the tenth position.
