Avoid bottom floats on pages with footnotes

Question

Following an old discussion about relative positioning of bottom floats and footnotes ("bottom floats above or below footnotes?"), I'd like to avoid altogether bottom floats on pages that also have footnotes.

Is it possible? Very simple question for a maybe hard answer.

Thanks in advance for any clue.

Answer 1

Based on the great answer from John Kormylo. This version is more robust: If the text with the footnote comes at the end of the page, John Kormylos version can break because a footnote after a pagebreak might suppress the float on the former page instead. This can be avoided by moving the code into the output routine:

\documentclass{book}
\usepackage[paperwidth=4.75in,paperheight=7.25in,
            textwidth=4.5in,textheight=6.5in,
            headsep=0.1in, footskip=0.15in,
            marginratio=1:1]{geometry}
\usepackage[latin,english]{babel}
\usepackage{graphicx}
\usepackage{booktabs,lipsum}

\toks0{\ifvoid\footins\else\suppressfloats[b]\fi}
\output\expandafter{\the\toks0\the\output}

\begin{document}

\selectlanguage{latin}
\chapter{Errora}

Tip of the hat to David Carlisle.

\documentclass{book}
\usepackage[paperwidth=4.75in,paperheight=7.25in,
            textwidth=4.5in,textheight=6.5in,
            headsep=0.1in, footskip=0.15in,
            marginratio=1:1]{geometry}
\usepackage[latin,english]{babel}
\usepackage{graphicx}
\usepackage{booktabs,lipsum}

\let\oldfootnote=\footnote
\def\footnote{\suppressfloats[b]\oldfootnote}

\begin{document}

\selectlanguage{latin}
\chapter{Errora}
