### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Formatting float and double values with max_digits10 preserves
round-trip precision but emits redundant digits such as
1.1000000000000001. Use fmt Dragonbox shortest-round-trip formatting in
BE and bit-exact matching formatting in FE, and synchronize affected
tests and expected results.
### Release note
Float and double values now use shortest round-trip string formatting
consistently in FE and BE.
