The following project field types are supported:
Tital Digits and Total Decimal Places
for the real number when configuring the field. Total Digits is the total number of digits in the number and Total Decimal Places is the number of digits to the right of the decimal. If
an unacceptable value is entered into a real number field, such as a value
that includes alphabetical characters, has too many digits after the decimal
place, or is too wide for the field as it has been configured, FootPrints
generates a warning before you can leave the page.
