cleanup: fix conversion warning

Browse source 
Fix a pair of warnings, which annoyed me for a long time:
For some reasons prefs.bottompo2 is an integer (mbar)
whereas prefs.modpO2 is a float (bar). This results
in mixed integer/floating point arithmetics when
conditionally using either of them. And ultimately
a warning, when storing a mbar value as an integer.
Fix this by an explicit cast to int after converting
modpO2 to mbar.
