Operation of short to char

GNU Radio
1

Hi,

Just wondering if the operation of short to char is a bug or
intentional.
The most significant 8 bits of the short gets converted to char, ie:

0-255 (short) -> 0 (char)
256-511 (short) -> 1 (char)
512-767 (short) -> 2 (char)

This is not the operation I expected, but the unit test allows it to
work
this way, so I am confused.

Regards,

Stephen

I think that I posted something similar few weeks ago. I also didn’t
expect
that 0-255 short goes to 0 char, and spent like a day trying to figure
out
the bug, but at the end it is like that.

Oh, like the lower 8 bits are like additional precision “digits” that
are being truncated… I would not have expected that either. Comments in
the GRC XML file would be good…
