Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- You can use -fexcess-precision=16 if you don't want treating _Float16 and __bf16 as having excess precision. With excess precision, I think the above behavior is correct. You'd need (int) (__bf16) 257.0bf16 to get 256 even with excess precision.
