Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- This is a question about how to use GCC, not a bug report. Please use the gcc-help mailing list for such questions. But this isn't a GCC problem anyway, since the function you're looking for would be part of the C library, and GCC is just a compiler and doesn't include a C library. Glibc has strtof128 for this purpose.
