type byte in Basic

#1

Hi all,

in looking at https://ask.libreoffice.org/de/question/97628/base64-encodedecode/ I came across a problem with type "byte" in Basic and do not know whether it is a bug or not:

I want to write bytes to a file.
I use
dim oOutputStream as variant
oOutputStream = createUnoService("com.sun.star.io.SequenceOutputStream")
and later on
oOutputStream.writeBytes(...)

If I define dim nA as byte
then nA = 195 is OK, but writeBytes(array(nA)) fails
and nA = -61 fails, but writeBytes(array(-61)) works.

It seems a variable of type byte can have values in range [0..255], but writeBytes can only use values in range [-128..127].

I have used dim nA as variant in the end, but wonder about the different ranges.

Kind regards
Regina

Hi Stephan,

Wow! Identified as bug and fixed immediately. That is great.

Kind regards
