Values from TR 18037:2008 are: ``` USFRACT_FBIT 7 USFRACT_MAX 0.9921875UHR USFRACT_EPSILON 0.0078125UHR ``` The values are conforming though different, just checking whether this is intentional given that `SFRACT` are using the identical values from the TR (this same thing happens with all the other `unsigned` variants). https://github.com/llvm/llvm-project/pull/81207 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
