- The default floating-point representation in {fmt} uses the smallest
precision that provides round-trip guarantees similarly to other languages
like Java and Python. `std::format` is currently specified in terms of
`std::to_chars` which tries to generate the smallest number of characters
(ignoring redundant digits and sign in exponent) and may procude more
decimal digits than necessary.
