Use a packed 8-byte representation for duk_tval. The packed representation
|
|
represents non-number values as special IEEE double NaN values, and is only
|
|
possible for platforms with 32-bit pointers. When the packed representation
|
|
is not available, Duktape uses a 12-16 byte struct/union which is more
|
|
portable.
