Does the standard also contain some gdtoa-like functionality (string

converts back to the original number)?


I don't see anything about it in the latest draft I could find, at:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1778.pdf

The actual ISO/IEC TS 18661-1 standard costs too much for me.

This seems to be lacking from the standard library, and it is rather
non-trivial to implement efficiently.

It would be nice to have this capability in glibc. Emacs would use it. CurrentlyEmacs uses an inefficient algorithm to print floating-point numbers.
