sooo ...

the MSB of the difference will be 0 for positive difference and 1 for neg difference... add to that PBP offers the direct print of the value and sign : " SDEC Difference "

The sensor is a Bosch BMP085. The actual raw un-compensated pressure value at about 260m (where I live) is -24200 in SDEC. I'm not sure what the range of values is going to be yet, I need to work that out yet (from sea level to say 1000m).

I'll try out the SDEC Difference to see what it does too.
