// In some instances, it can happen that the rollValue & target are
// invalid inside the UAVObjects, and become a "nan" value, which freezes
// the PFD and the whole GCS: for this reason, we check this here.
// The strange check below works, it is a workaround because "isnan(double)"
// is not supported on every compiler.
