다음 좀 설명 꼭 부탁드립니다
무슨 뜻인가요?

void Sys_FloatTimeInit(void)
{
    LARGE_INTEGER    PerformanceFreq;
    unsigned int    lowpart, highpart;

    assert (QueryPerformanceFrequency (&PerformanceFreq));

    lowpart = (unsigned int)PerformanceFreq.LowPart;
    highpart = (unsigned int)PerformanceFreq.HighPart;
