C++
virtual int precision() const;
Description
The implementation of this function is dependent on the intended use of the filer.
For the ObjectARX internal filer that handles DXF file I/O, this function always returns AcDb::kDfltPrec (a value of -1) when filing in. When filing out, if the filer's setPrecision() method (see AcDbDxfFiler::setPrecision()) has not been called, then AcDb::kDfltPrec is returned, otherwise the precision set by the last call to setPrecision() is returned.
For the ObjectARX internal filer that handles AutoLISP or C++ function I/O, this function always returns AcDb::kDfltPrec.
The default implementation of this method is to return AcDb::kDfltPrec.
