If we know we are rounding to nearest, we can use fast path in more cases as before. The following patch merges those changes into libstdc++. 2022-11-24 Jakub Jelinek <ja...@redhat.com> PR libstdc++/107468 * src/c++17/fast_float/MERGE: Adjust for merge from upstream. * src/c++17/fast_float/fast_float.h: Merge from fast_float 2ef9abbcf6a11958b6fa685a89d0150022e82e78 commit.
