-### converted_type
-
-The `converted_type` is the resulting type of the converted value. It lets consumers of the converted value know the resulting type. In our case we're doubling the input value and since this could be applied to an unsigned integer as well as a floating point value we'll choose `FLOAT`.

-### converted_bit_size
-
-The `converted_bit_size` is the resulting size of the converted value. It lets consumers of the converted value know the resulting size. Since we chose `FLOAT` as the type we'll choose `32` as the bit size. We could have also chosen `64` bits. Sometimes you know the type and size of the resulting conversion and can simply hard code them. Other times you need to pass them in as parameters and let the user decide.
