Property Value

The default value of this property is null.

Remarks
ValuePrecision can be used for the following DataTypes: The ValuePrecision property is an approximation that is intended to provide guidance to a client. A server is expected to silently round any value with more precision that it supports. This implies that a client may encounter cases where the value read back from a server differs from the value that it wrote to the server. This difference shall be no more than the difference suggested by this property.
