Summary
ktoml parses all TOML floats into Double, which loses the original text representation. Scientific notation 5e+22 may become 50000000000000000000000.0 after round-trip. While the value is preserved, the representation is not.
This is analogous to how ktoml already tracks IntegerRepresentation (DECIMAL, HEX, OCTAL, BINARY) for TomlLong — but no such tracking exists for floats.
Affected toml-test cases (2)
Found via toml-lang/toml-test compliance suite:
valid/float/exponent.toml — scientific notation valuesvalid/spec-1.0.0/float-0.toml — mix of decimal and scientific
Suggested fix
Add a FloatRepresentation enum (DECIMAL, SCIENTIFIC) similar to IntegerRepresentation, and store it in TomlDouble. The writer uses it to choose the output format.
