--- Comment #6 from anders at wahrzeichnen dot de <anders at wahrzeichnen dot de> --- (In reply to jos...@codesourcery.com from comment #3) > This is as specified in the C standard. I guess you are referring to the C18 section 6.3.1.8 (2) "The values of floating operands and of the results of floating expressions may be represented in greater range and precision than that required by the type; the types are not changed thereby. --footnote: The cast and assignment operators are still required to remove extra range and precision." in conjunction with 6.6 (5) "An expression that evaluates to a constant is required in several contexts. If a floating expression is evaluated in the translation environment, the arithmetic range and precision shall be at least as great as if the expression were being evaluated in the execution environment. --footnote: The use of evaluation formats as characterized by FLT_EVAL_METHOD also applies to evaluation in the translation environment." If so, I propose to close this bug (as __FLT_EVAL_METHOD__ is indeed 2).
