Re: [Discuss-gnuradio] Operation of short to char

[Monahan-Mitchell, Tim]

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…

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.

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
