MulDiv

int MulDiv(int nNumber, int nNumerator, int nDenominator);
//nNumber * nNumerator / nDenominator

사용예)
    TRACE("%d", 12*34/12);
        //출력 = 34
    TRACE("%d", 1234567*8900000/1234567);
        //출력 = 907
    TRACE("%d", MulDiv(1234567, 8900000, 1234567));
        //출력 = 8900000
    TRACE("%ld", (LONGLONG)1234567*8900000/1234567);
        //출력 = 8900000
    TRACE("%d", MulDiv(1234567,8900000,0));
        //출력 = -1

각각의 차이점은??? ^^;
