AFAIK, generally, such binary (file-, Network transfer, ) formats

TStream is basically an abstraction for stream of bytes. The read
methods are just convenience, not some protocol.

var d : double; // or single, avoid extended
d:=;
stream.write(d,sizeof(d));
stream.read(d,sizeof(d));
All the stream helpers are just that.
One could add writedouble/

Depends on size constraints.

As
procedure TStream.WriteQWord(q: QWord);
begin
WriteBuffer(q,8);

it's rather easy to do

I use FloatStr() to do the conversion, then Write() to actually write it
to a stream.

Hi all.
What is the best/preferred way to write floatingpoint to a steam?
Since TStream doesn't have any native WriteFloat/Double and the likes,
some conversion is needed - but what is a good strategy for this?
A simple conversion like Stream.WriteDWord( DWord(variable>)) is not possible due
