Addresses FR 35


Instantiations of the class template complex<> have to be allowed for integral types, to reflect existing practice and ISO standards (LIA-III).


[ 2009-10-26 Proposed wording in N3002. ]

[ 2010 Pittsburgh: ]

Moved to NAD Future. Rationale added.

[LEWG Kona 2017]

Recommend SG6

[2017-03-03, Kona]

SG6 suggests this issue is a new feature, not a problem with the existing standard, and should therefore be closed NAD. However, SG6 invites papers that bring the proposal up to date with the current standard.


There is no consensus for making this change at this time.

Proposed resolution:

Adopt N3002.
