When pre-defining a structure using a union, how to tell compiler what element to place the value into?

Consider this code:

>struct MyStruct
>    union
>    {
>        int i;
>        float f;
>    } value;
>MyStruct Values[] =
>    300L,
>    10.0f,
>    15.0f,

Now the 10.0f, and the 15.0f values are converted to integer, and placed into the union. How, if possible, to make them remain as floats and then placed into the union. I tried using a void * in the union as the first field, but the compiler wont convert floats to void *.

Anonymous union or not, the values still are converted to the first type in the union.

struct MyStruct
    MyStruct(float f)
        value.f = f;

    MyStruct(long i)
        value.i = i;

        int i;
        float f;
    } value;
