[Bug c++/98202] C++ cannot parse F128 suffix for float128 literals
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98202 --- Comment #5 from Jonathan Wakely --- Q can't be used with -std=c++NN strict modes, as noted in bug 87274 limits:2085: error: unable to find numeric literal operator 'operator""Q'

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98202 Jakub Jelinek changed: What|Removed |Added CC||jakub at gcc dot gnu.org --- Comment #4 from Jakub Jelinek --- Other option would be just hardcode those 4 constants by hand: #define __FLT128_MAX__ 1.18973149535723176508575932662800702e+4932F128 #define __FLT128_NORM_MAX__ 1.18973149535723176508575932662800702e+4932F128 #define __FLT128_MIN__ 3.36210314311209350626267781732175260e-4932F128 #define __FLT128_EPSILON__ 1.92592994438723585305597794258492732e-34F128 #define __FLT128_DENORM_MIN__ 6.47517511943802511092443895822764655e-4966F128 with __extension__ before it and Q suffix instead of F128. For __float128 I think those constants aren't going to change. Advantage of doing that would be that even various versions of clang++ support that, while F128 suffix isn't supported. So, use: (__extension__ 0x1.p+16383Q) (__extension__ 0x1.p+16383Q) (__extension__ 0x1.p-16382Q) (__extension__ 0x1.p-112Q) (__extension__ 0x0.0001p-16382Q) instead of those 4 constants.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98202 Jonathan Wakely changed: What|Removed |Added Resolution|--- |DUPLICATE Status|UNCONFIRMED |RESOLVED --- Comment #2 from Jonathan Wakely --- I suppose we can combine them. This one is about the internal macros, which do not require -std=gnu++NN modes, and they fail to compile even if you use a gnu++NN mode. The other bug only fails for strict c++NN modes. *** This bug has been marked as a duplicate of bug 87274 ***
