Bug ID: 58412
Summary: C++11 : numeric_limits::stuff must be constexpr
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pierreblavy at yahoo dot fr
Hello,
numeric_limits::stuff must be constexpr, as required by the C++11 standard
see the C++11 section in
http://www.cplusplus.com/reference/limits/numeric_limits/
Such behaviour is required to use this values as static const variables, or as
default variables for functions.
e.g.
struct A{
static constexpr double NaN=std::numeric_limits<double>::quiet_NaN;
f(double d=NaN){};
};
