Then when I refactored it in r14-1582-g6261d10521f9fd I used the value calculated from the incorrect value (35 instead of 36). libstdc++-v3/ChangeLog: PR libstdc++/121374 * include/std/limits (numeric_limits<__float128>::max_digits10): Fix value. * testsuite/18_support/numeric_limits/128bit.cc: Check value.
