[PATCH] D66836: [libc++] Add `__truncating_cast` for safely casting float types to integers

[Steve Canon via Phabricator via cfe-commits]

scanon added inline comments.


================
Comment at: test/libcxx/numerics/truncating_cast.pass.cpp:36
+      {static_cast<double>(Lim::max()) + 1, Lim::max(), false},
+      {static_cast<double>(Lim::max()) + 1024, Lim::max(), false},
+  };
----------------
Probably should test `nextafter(static_cast<double>(Lim::max()), INFINITY)` here instead.
