__property float AsSingle = {read=GetAsSingle, write=SetAsSingle};
Description
Represents the field's value as a Single floating-point number.
Use AsSingle to read the value of the field's data into a Single or to assign a Single value to the contents of the field. TField does not support Single floating-point values and raises an exception when an attempt is made to get or set the AsSingle property.
Descendants of TField that represent Single floating-point numeric fields or that support conversions between the field's Value property and a single value override AsSingle to read and write the value of the field as a 7 digits of precision floating-point number.
