shortest_double()

std::string raptor::shortest_double

(

double const

value

)

Returns the shortest representation of value that reads back as the same double.

Uses std::to_chars, e.g. 0.05 and 1, not 0.050000 and 1.000000. Not finite values yield nan, inf and -inf, which are not valid JSON; raptor::json_writer::number writes null instead.
