Hi, I have a struct that has a long double member.

After using BINLOG_ADAPT_STRUCT and logging the struct member, when the output file is read using bread, there is some loss of precision.

e.g. 1234234.0234242 becomes 1.23423e+06.

Is there a way to control the precision that is being printed by bread?
