If we print out the pressure difference (because we do not have a cylinder size), we didn't initialize the precision. We should print out pressures without decimals. The attached patch fixes that, and also avoids a NULL pointer printout (which on Linux will just print out "(null)") if there is no cylinder type descriptor string. It also cleans things up a bit and uses the "cyl" pointer instead of repeating the "dive->cylinder[n]" thing.
