Resolves #14021.
Most of the code was adapted from my previous shard implementation to ensure it conforms to the IEEE standard.
For printing, this is not enough for
sprintf "%a"
, because things like precision and alternate format aren't available yet. For parsing, thewhitespace
andstrict
parameters can be added later, as they don't interfere with the contents within a hexfloat, only with the surrounding characters.
