Why does this not produce y tick labels in fixed number format? (pgfplots version 1.9 produces y tick labels in scientific format)
\documentclass[12pt]{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[y tick label style={/pgf/number format/fixed}]
\addplot{cos(x)/12.0};
\end{axis}
\end{tikzpicture}
\end{document}

scaled y ticks=falsedoes what I want, but I'll accept your answer regardless. – JPi Sep 10 '14 at 00:04
