also: - fixed truncation of floating-point values when using ostreams - fixed some minor documentation issues (fixes #8) - fixed missing value deduction guides for dates and times - added serialization round-trip tests (closes #9) - added node::is_number() - added node_view::is_number() - added node_view::value_or() (closes #7) - added hexfloat parsing support for all implementations, not just <charconv> ones
