--- Comment #4 from Rich Felker <bugdal at aerifal.cx> ---
Comment 1 is wrong; the quoted text only applies to implementations which do
not attempt to conform to Annex F, whereas clang/llvm does. The directly
relevant text is F.3 ¶1: "The +, -, *, and / operators provide the IEC 60559
add, subtract, multiply, and divide operations."
