  • [SOLVED] Project Setting "Treat 'double' as 'float"

    Hello Segger Team,


    How is the Project setting „Treat 'double' as 'float'” working? When enabled it should handle variables of type double as they were float.

    In my tests float is always 32 bits in size, and double 64 bits regardless of how this project option is set. Compare my tiny example.


    Best regards

  • Hello,

    Thank you for your inquiry.
    This is unfortunately a deprecated project option which will be removed.
    It was available with gcc in the past, but they removed it form the compiler. Clang never had it.

    Sorry for the confusion.

    Best regards,
    Nino

  • Hello Nino,


    thanks for the clarification.

    I was a bit worried as the default is that doubles are treated as float, and I need to have doubles in my application.

    If I have understood you correctly, this is a dead option without any impact, right?
