Hello, I am the technical version of you |

I've measured the impact of this bug as well as the potential benefit by the fix in my repo. https://github.com/DesWurstes/comparefloats I can't comment under the bug on Sourceware since I don't have an account there |

Fixed in both GCC and Glibc, this can be closed now Thank you Jason for posting the link to my repository Thank you Jakub for committing the fix |

Dear Jason @jicama The broken constant still remains in sysdeps/ieee754/ldbl-128ibm/e_expl.c could you please ask Jakub to apply the patch here as well? |
