TWriter.WriteDouble Method

Writes a value of type Double to the writer object’s stream.

Pascal
procedure WriteDouble(const Value: Double);
C++
__fastcall WriteDouble(const Double Value);

WriteDouble is used internally by the component streaming system to write component properties to a stream. Use WriteDouble to write a value of type Double to the writer object’s stream. 

WriteDouble checks to ensure that Value is the correct type before calling Write to write the float value and its value type to the stream.
