PVS-Studio warning V636 for OpenDDS

inline ACE_UINT32
ACE_CU64_TO_CU32 (ACE_UINT64 n)
{
  return static_cast<ACE_UINT32> (n);
}

inline void
Latency_Stats::dump_results (const ACE_TCHAR *test_name,

  ....
  double min_usec = ACE_CU64_TO_CU32 (this->min_) / gsf;

}

This suspicious code was found in OpenDDS project by PVS-Studio static code analyzer.
Warning message is:
V636 The 'ACE_CU64_TO_CU32(this->min_) / gsf' 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;. latency_stats.h 73
