--- Comment #3 from g.peterh...@t-online.de --- But in your documentation https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html it is stated that the __builtin's would be available for all FP types. For upcoming standards https://en.cppreference.com/w/c/experimental/fpext1 this is needed anyway (setpayload etc.) thx Gero
