Subject: [Bug c++/110476] constexpr floating point regression with -std=c++XX
Date: Thu, 29 Jun 2023 11:02:30 +0000	[thread overview]
Message-ID: <bug-110476-4-7JntFYZybo@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #2 from Peter Dimov <pdimov at gmail dot com> ---
Discussion of FLT_EVAL_METHOD notwithstanding, I think that this behavior is
not allowed by https://eel.is/c++draft/lex.fcon#3.

"If the scaled value is not in the range of representable values for its type,
the program is ill-formed. Otherwise, the value of a floating-point-literal is
the scaled value if representable, else the larger or smaller representable
value nearest the scaled value, chosen in an implementation-defined manner."

I don't see any license here for the value of 3.14f to be 3.14L.
