The
isDecimalDigit verification property
determines whether to check that the input value includes only valid
decimal digits, which may be any of the following characters:
- Numeric characters 0-9
- A negative sign (-)
Valid values are NO (the default) and YES.
This property applies only to character fields.
If you want to allow more characters such as the decimal character
(a period or a comma) and the separator character (a comma or a period)
as the input value, use one of the following ways:
- Specify the field type as NUM rather than char;
- Ensure that the isDecimalDigit = YES form field is ignored. To
ignore that field, set the symbolic parameter IGNOREISDECIMALFORCHARFIELD
to YES.
