YAML scalars tagged `!!float` were round-tripped through `float64` and re-serialized by Go's JSON encoder, which strips the decimal part of whole-number floats. As a result, `50.0` came out as `50` and a sequence like `[50.0, 95.0, 99.0, 99.9]` became `[50,95,99,99.9]`, turning a uniform array of floats into a mixed int/float array that downstream consumers (Horreum, JSON Schema validators, jq, etc.) reject. The JSON spec does not distinguish ints from floats, but every common JSON library (Go's `encoding/json`, Python's `json`, jq) preserves the fractional form of values that came in as floats. yq's YAML decoder already parses these as `!!float` with the original text intact, so we can emit them verbatim instead of round-tripping. `MarshalJSON` for `ScalarNode` now special-cases `!!float`: - if `Value` is already a JSON-shaped number literal containing a `.` or exponent, emit it verbatim (e.g. `50.0`, `99.9`, `1.5e-3`, `-7.0`); - if `Value` is an integer-shaped string tagged `!!float` (e.g. `!!float 5`), format the parsed float and append `.0` so it stays a JSON number with a fractional part; - otherwise (empty value, parse error, or non-finite result), fall back to the existing encoding path so behaviour for `.inf` / `.nan` and anything unusual is unchanged. `!!int` nodes still encode as JSON integers.
