that equated to 64 bits of precision for the mantissa, and 16 bits for the exponent and sign - the remaining 2 bytes being unused

Ah! That makes a (little) sense of it.

It'd be interesting to see a quick comparison of the performance of 64-bit .v. 80-bit .v. 128-bit. The latter must be an order of magnitude or more slower than the other two?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
