Re: [boost] [serialization] Serialisation/deserialisation offloating-point values

Note the difference between the "definition" formulae of 3010/10000 and the suggested formulae using 3030/10000. Perhaps this is on purpose, if not may explain why the tests done later in this thread wich use the 3030/10000 version had troubles? ;;peter Paul A Bristow wrote:

[...] For C++, using numeric limits,

So it is convenient instead to use the following formula which can be calculated at compile time: 2 + std::numeric_limits<double>::digits * 3010/10000;

[...] and I suggest that this should be:

os << std::setprecision(2 + std::numeric_limits<double>::digits * 3030/10000);
