PVS-Studio warning V636 for QT

typedef struct tagORIENTATION {
  int orAzimuth;
  int orAltitude;
  int orTwist;
} ORIENTATION, *PORIENTATION,
  NEAR *NPORIENTATION, FAR *LPORIENTATION;

bool QWindowsTabletSupport::translateTabletPacketEvent()
{
  ....
  const double radAzim =
    (packet.pkOrientation.orAzimuth / 10) * (M_PI / 180);
  ....
}

This suspicious code was found in QT project by PVS-Studio static code analyzer.
Warning message is:
V636 The 'packet.pkOrientation.orAzimuth / 10' expression was implicitly casted from 'int' type to 'double' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. qwindowstabletsupport.cpp 467
