To see and test any fixes the problem, view the page in a mainstream browser like Chrome, Safari, or IE/Edge (rather than in one of the minority browsers like Firefox, which, when requisite fonts are installed, uses local MathML processing.

:Huh? Firefox is a "minority" class browser? But yes, I have just dabbled with IE8 and indeed the formula is not rendered, instead there appears a box with a big red cross in it. Much the same happens when IE8 is pointed at wikipedia's Fibonacci_number article where their formulae do not appear either. The W. formula is slightly different and possibly I rearranged it a little - I don't quite recall where I found it, but I never expected this inability! Similar formula preparation language has been available in OpenOffice's text editor for some years now, for example, and I ~~though~~ it relatively standard. However, via mathproofs.blogspot.com I've found an image of the formula, but I'm not familiar with inserting such into Rosettacode... I could of course rewrite the formula in Fortran source style, but that lacks the far more pleasing layout and glyphs of the mathematical formula.

:: Yes, Firefox happens to be in the minority in respect of how it handles formulae (local processing of MathML, where requisite fonts are available) – most browsers currently take the route of displaying the graphic file – perhaps because of the font dependency issue). Support for the MathML route is at about 25%, and excludes Chrome, IE/Draft, and Safari. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 10:49, 25 September 2016 (UTC)
