--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
In r14-1582-g6261d10521f9fd I did:

-      static _GLIBCXX_USE_CONSTEXPR int max_digits10
-       = __glibcxx_max_digits10 (112);
+#if __cplusplus >= 201103L
+      static constexpr int max_digits10 = 35;
+#endif


But that was already wrong because it used 112 not 113, which was present since
r14-1433-gf150a084e25eaa for PR 104772

Dunno where I got 112 from, maybe just a typo.
