Description

TExtendedField represents a field that contains the highest precision floating point value in a dataset.

TExtendedField encapsulates the fundamental behavior common to fields that contain the highest precision floating point data. Extended fields can hold values in the range 3.37 x 10^-4932 to 1.18 x 10⁴⁹³², and are frequently used to floating point values where the highest precision is required.
