Should have been:

-----
I would like the compiler to determine the union member by its type
when possible.

struct SExample
{
    union {
        int i;
        float f;
    };
};

SExample myArray[] =
{
    { 10 }, // Initialized to i member as int
    { 3.14f } // Initialized to f member as float
};

Also, on conflicting types, such as 5 for int and
char, if the bytes they occupy would all map to
the same location in the union, the cast would
not be required.

Best regards,
Rick C. Hodgin
