    @mkdir Qt Creator 12.0에서 생긴 버그 같습니다. 12.0.1로 업그레이드해도 여전히 이 문제가 해결된 것 같지는 않습니다.

    @hlowd said in ShellExecute 사용 관련 문의:

    코드로 scp 명령을 수행해야 하는데 해결 방법이 있을까요?
    ps) qprocess로 실행 시 scp 명령이 유효하지 않는 것 같습니다.

    I need to run the scp command with the code, is there any workaround?
    P.S. The scp command doesn't seem to be valid when executed with qprocess.

    (translated with DeepL)

    If you want to start a QProcess and run scp do something like this:

    QProcess process; // Path to your scp, wherever it is... // e.g. C:/Windows/System32/OpenSSH/scp.exe QString command = "C:/Program Files/Git/usr/bin/scp.exe"; // you need full path to scp.exe here // or register in PATH variable on your system so that Windows knows the "scp" command and where the program is located QStringList params; params.append("‪/C/Path/to/File"); params.append("‪user@host:/C/Destination/Path/"); process.start(command, params, QIODevice::ReadWrite);

    @hlowd said in double 소수점 계산 관련 문의:

    더해지는 값을 double 형 변수에 저장하는 것은 어려울까요?

    Sure, you can convert the results to floating point numbers at any stage - eg inside the loop, or a the very end. For example:

    #include <iomanip> #include <iostream> int main() { uint64_t a = 25; uint64_t sum = 0; for(int i = 0; i < 100000; i++) { sum += a; const double sumAsFloat = sum/100000.0; std::cout << (sum/100000) << '.' << std::setfill('0') << std::setw(5) << (sum%100000) << std::setprecision(10) << " \t[" << sumAsFloat << ']' << std::endl; } }

    Outputs:

    0.00025 [0.00025] 0.00050 [0.0005] 0.00075 [0.00075] 0.00100 [0.001] 0.00125 [0.00125] 24.99900 [24.999] 24.99925 [24.99925] 24.99950 [24.9995] 24.99975 [24.99975] 25.00000 [25]

    Cheers.

    PS: In printing both the uint64_t and double versions side-by-side, I realised there's was a small error in my previous reply, where the (sum%10000) should have had another 0, ie (sum%100000). I fixed that in the code in this reply :)
