The precision is set in basic_text_oprimitive.hpp line 139. with the statement: os << std::setprecision(std::numeric_limits<double>::digits10 + 2); I believe that std::numeric_limits<double>::digits10 returns the number of digits required to hold the maximum value in base 10. So either a) I misunderstand the function and/or application of std::numeric_limits b) its incorrectly implemented on your platform c) you think you have more precision than you actually do. look into this and check back Robert Ramey Adam M wrote:
Hi,
I am using Boost.Serialization to serialize a std::map<std::string, double>.
It works fine, except that the precision on the double is not enough for my application.
Is it possible to manipulate the precision used when serializing/deserializing double's within an STL container? I tried using setprecision(), but it doesn't understand the "&" stream operator that the Serialization library uses.
Thanks, Adam
