Someone reported the same post on the cpython tracker, and I've just filed a separate issue about this idea. http://bugs.python.org/issue12450 Note that cpython2.7 (and pypy 1.5) already uses a specific algorithm to convert float to strings: a slightly customized version of David Gay's dtoa.c: http://www.netlib.org/fp/dtoa.c it is already faster and more accurate than many libc implementations. -- Amaury Forgeot d'Arc _______________________________________________ pypy-dev mailing list [email protected] http://mail.python.org/mailman/listinfo/pypy-dev
