I put a lot of time into figuring out how to have the page numbers on the long side of my landscape pages as per my school's formatting requirements (yes I'm sure) but now the numbers are apparently slightly too high. I need to make it 0.5 inch from the bottom of the page and centered in order to get my PhD. (I'm not bitter...)

Current code:

usepackage{pdflscape}

usepackage{fancyhdr}

usepackage{floatpag}

....





fancypagestyle{floatpage}{%

  fancyhf{}% Clear page header/footer

  fancyfoot{

    makebox[textwidth][r]{% Right

      rlap{hspace{footskip}% Push out of margin by footskip

        smash{% Remove vertical height

          raisebox{dimexpr.7baselineskip+footskip+.5textheight}{% Raise vertically

            rotatebox{90}{thepage}}}}}}% Rotate counter-clockwise

  renewcommand{headrulewidth}{0pt}% No header rule

  renewcommand{footrulewidth}{0pt}% No footer rule

}

And then for the figure:

 begin{landscape}

 begin{figure}  

centeringthisfloatpagestyle{floatpage}%

    begin{subfigure}{.6textwidth}

        centering

        includegraphics[width=linewidth]{chapters/ProgrammedCellDeath/lyse_benefit.pdf}

        caption{Science}label{helping}

    end{subfigure} %

    begin{subfigure}{.6textwidth}

        centering

        includegraphics[width=linewidth]{chapters/ProgrammedCellDeath/explode_benefit.pdf}

        caption{Science}label{harming}



    end{subfigure} 

caption{Science is cool.}

end{figure}

end{landscape}

This code did the trick:

  fancypagestyle{floatpage}{%

  fancyhf{}% Clear page header/footer

  fancyfoot{

    makebox[textwidth][r]{% Right

      rlap{hspace{footskip}% Push out of margin by footskip

        smash{% Remove vertical height

          raisebox{dimexpr6baselineskip+footskip+.5textheight}{% Raise vertically

            rotatebox{90}{thepage}}}}}}% Rotate counter-clockwise

  renewcommand{headrulewidth}{0pt}% No header rule

  renewcommand{footrulewidth}{0pt}% No footer rule

}

Just changed the dimrexp.7 to dimrexp6 though I still have no real clue as to why that worked and would love an explanation.

The exact position is a little complicated to calculate. Assuming we start at the right-hand side of the footer, then we want a vertical box centered at .5textheight + footskip above the baseline of the footer. This needs to be pushed to the right by the width of the margin and then moved back on to the page by .5in. The width of the margin is

pagewidth-textwidth-1in-hoffset-oddsidemargin

(have a look at the diagram in the fancyhdr documentation)
Putting this together we get:

documentclass{article}



usepackage{fancyhdr}

usepackage{rotating}

usepackage{floatpag}

usepackage{graphicx}

usepackage{subcaption}



fancypagestyle{rotfloatpage}{%

fancyhf{}%

rfoot{makebox[0pt]{smash{rotatebox{90}{%

  makebox[dimexprtextheight+2footskip]{%

  raisebox{dimexprtextwidth+1in+hoffset+oddsidemargin-paperwidth

  +.5inrelax}[0pt][0pt]{thepage}}}}}}%

renewcommand{headrulewidth}{0pt}%

renewcommand{footrulewidth}{0pt}%

}



rotfloatpagestyle{rotfloatpage}



begin{document}



begin{sidewaysfigure}

  centering

  begin{subfigure}{.49textwidth}

    centering

    includegraphics[width=textwidth]{example-image-a.jpg}

    caption{Science}label{helping}

  end{subfigure} %

  begin{subfigure}{.49textwidth}

    centering

    includegraphics[width=textwidth]{example-image-b.jpg}

    caption{Science}label{harming}

  end{subfigure}

  caption{Science is cool.}

end{sidewaysfigure}



end{document}

Note I have used the rotating package rather than pdflscape as in combination with floatpag one set the corresponding page style for all such floats at once.
