Hello:intel does little Endian..
I have a question that I hope someone experienced with Delphi can
answer...
I am using a program to read a binary file that was written in Delphi.
The data is Delphi's extended
precision type, which is 10 bytes. I need to convert those over to a
double precision number (8 bytes)
Here's the question: exactly how does the Delphi compiler interpret
those 10 bytes? I'll take a step
back....I know that the actual readfile is done by a win32 call
through windows app. So I guess
I have 2 questions:
1 - How are the bytes ordered when they are read in? This is critical
because I am reading
in a byte at a time (as U8)
2 - What is the ordering of the bytes....The endian-ness?
I have an algorithm to convert the byes that constitute the extended
precision to doubles,
but I guess it won't be very useful if I cannot get the byes ordered
correctly!
Thank you for any help!
Regards, Gary.
which means, the first byte in memory is the low part of the item..
being it was done via delphi, I would say it's also read/written that
way to file.
