Description

Represents the field's value as a high-precision floating-point number.

Use AsExtended to read the value of the field's data into an Extended, or to assign an Extended value to the contents of the field. TField does not support high-precision floating-point values and raises an exception when an attempt is made to get or set the AsExtended property.

Descendants of TField that represent high-precision floating-point numeric fields or that support conversions between the field's Value property and an Extended value override AsExtended to read and write the value of the field as a high-precision floating-point number.
