Format a JSON string

Hi there,

I convert a std::vector<std::vector<float>> to a JSON string. Basically it
works, but the format is scientific:
"[[1.017E3,1.017E3,1.017E3 ... ]]"

My method looks now like this:

std::string Class::convertFieldAsJSON(std::vector<std::vector<float>> field) {
  return boost::json::serialize(boost::json::value_from(field));
}

It works, but my colleagues want to see a 1017 and not 1.017E3 in the output.
Is there a way to format the string?

Thanks in advance,
Markus
