Thank you for the reply.
After 3 hours trials and reading the source code of Postgres backend, now I
can figure out a way to transfer float data from sever to client and then
write back to server *without lose any precision*.
At server part, it uses strtod to convert received string to float valu

Hi!
In C Language, there is a way to format float numbers into a hex string by
using "%a" in printf.
eg:
the value: 1.2345 can be expressed as '0x1.3c083126e978dp+0' which is the
hex representation of a float number.
I have tried this in Postgres:
SELECT '0x1.3c083126e978dp+0'::float;
float8
