Discussion:
With the acceptance of gcd
and lcm
in the working draft, the same problem as pointed out by
LWG 2733(i) exists here as well and should be fixed accordingly.
[2016-08, Chicago]
Monday PM: Moved to Tentatively Ready
Proposed resolution:
This wording is relative to N4606.
Adjust 27.10.14 [numeric.ops.gcd] p2 as indicated:
template<class M, class N> constexpr common_type_t<M, N> gcd(M m, N n);[…]
-2- Remarks: If eitherM
orN
is not an integer type, or if either is (possibly cv-qualified)bool
, the program is ill-formed.
Adjust 27.10.15 [numeric.ops.lcm] p2 as indicated:
template<class M, class N> constexpr common_type_t<M, N> lcm(M m, N n);[…]
-2- Remarks: If eitherM
orN
is not an integer type, or if either is (possibly cv-qualified)bool
, the program is ill-formed.
