Handle a < 0 ?

The problem is perfectly well defined for a < 0, but many of the implementations (e.g. the C version and translations thereof) do not handle this case correctly. Is this a bug in the implementations or in the problem specification.

It seems to be neither Steven. You don't have to consider a < 0 to answer the example given in the task description. --Paddy3118 (talk) 16:45, 14 November 2013 (UTC)

Formulae hidden to most browsers by under-tested cosmetic edits at 19:16, 15 July 2016

Under-tested cosmetic edits made to the task page at 19:16, 15 July 2016, including the injection of spaces around expressions in <math> tags, have left the task description formulae completely invisible to all browsers which display the graphic file version of formulae rather than processing the MathML (this is, in fact, the majority of browsers). The MediaWiki processor does not currently expect such spaces, and generates syntactically ill-formed HTML if they are introduced. Other aspects of these cosmetic edits may further compound the problem. Hout (talk) 21:17, 22 September 2016 (UTC)
