Converting a series of numbers into a 64 bit binary frame..?

Hmmm. I can't recall if you participated in the same discussion in the other thread. In that one, and others, unions have been identified as producing undefined behavior when used this way, and non-portable due to undefined implementation details.

I have not read through the other discussion, but instead of a union, using memcpy to copy an 8-byte array into a uint64_t should work.
