How to handle overflows of int16

4 views (last 30 days)
I get a vector of int16 from a VISA-instrument where the values have rolled over if to big, the vector has an offset that I want to subtract but then the values just becomes floored at - 32768.
The question comes down to how can I make int16(-2^15-1) = 32767 ?
