-// number was found, but it was out of the representable range of the requested
-// type, or to std::errc() otherwise.
-//
-// If a well-formed number was found, `ptr` is set to one past the sequence of
-// characters that were successfully parsed.  If none was found, `ptr` is set
-// to the `first` argument to from_chars.

-// Workalike compatibilty version of std::from_chars from C++17.  Currently
-// this only supports the `double` and `float` types.
-//
-// This interface incorporates the proposed resolutions for library issues
-// DR 3080 and DR 3081.  If these are adopted with different wording,
-// Abseil's behavior will change to match the standard.  (The behavior most
-// likely to change is for DR 3081, which says what `value` will be set to in
-// the case of overflow and underflow.  Code that wants to avoid possible
-// breaking changes in this area should not depend on `value` when the returned
-// from_chars_result indicates a range error.)
-//
-// Searches the range [first, last) for the longest matching pattern beginning
-// at `first` that represents a floating point number.  If one is found, store
-// the result in `value`.
-//
-// The matching pattern format is almost the same as that of strtod(), except
-// that C locale is not respected, and an initial '+' character in the input
-// range will never be matched.
-//
-// If `fmt` is set, it must be one of the enumerator values of the chars_format.
-// (This is despite the fact that chars_format is a bitmask type.)  If set to
-// `scientific`, a matching number must contain an exponent.  If set to `fixed`,
-// then an exponent will never match.  (For example, the string "1e5" will be
-// parsed as "1".)  If set to `hex`, then a hexadecimal float is parsed in the
-// format that strtod() accepts, except that a "0x" prefix is NOT matched.
-// (In particular, in `hex` mode, the input "0xff" results in the largest
-// matching pattern "0".)
