[Cfp-interest 1719] Re: short hex strings

[David Hough CFP]

Sounds good to me

+++++++++++++++
This implementation choice affects numerical values printed with a precision P 
that is insufficient to represent all values exactly. 
Implementations with different conventions about the most significant 
hexadecimal digit will round at different places,
affecting the numerical value of the hexadecimal result. 
Portable code seeking identical numerical results on different platforms 
should avoid precisions P that require rounding.
