Comment (by Mike Taves):

 Thanks for introducing Ryu, as I haven't seen this yet. It appears to be a
 possible successor to Google's [https://github.com/google/double-
 conversion double-conversation].

 Another good resource on the same topic is from
 [http://www.ryanjuckett.com/programming/printing-floating-point-numbers/
 Ryan Juckett], with an implementation called Dragon4, which is now used by
 numpy to format floats to
 [https://docs.scipy.org/doc/numpy/reference/generated/numpy.format_float_positional.html
 positional] or
 [https://docs.scipy.org/doc/numpy/reference/generated/numpy.format_float_scientific.html
 scientific] notation strings. It's a shame there is no direct comparison
 between Dragon4 and Ryu, although I will say the publication for Ryu
 presents itself well.
