Line 31:
: If you wish to test whether a complex number is an integer you also need to be careful to state what you mean by that term. A complex integer, more usually termed a ''Gaussian integer'' or an element of the ring '''Z'''[''i''], is an ordered pair of elements (''re'', ''im'') of the ring '''Z''', the ring of integers. The sub-ring which has ''im'' = 0 is isomorphic to '''Z'''. My ''guess'' is that the latter set is what is meant when the task is extended to treat complex numbers but this should be made explicit.

==Number set symbols not visible to most browsers==
Browsers which display a graphic file (rather than locally processed MathML and local fonts) for the content of <math> tags are not displaying number set symbols on the task page, because the MediaWiki processor is choking on unexpected input and generating syntactically ill-formed HTML tags (in which a semi-colon is missing between the height and vertical-align attributes).
May be worth further investigation and testing of the expectations of the MediaWiki processor here. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 19:25, 21 September 2016 (UTC)
