Constant number of decimal places EXCEPT 0

Question

I am working with pgfplots and I want a constant number of decimal places on ticks. A similiar question was answered here pgfplot with constant decimal places on ticks

\usetikzlibrary{shapes,arrows}
\usepackage{pgfplots,pgfplotstable,tikz}
\usepgfplotslibrary{external}
\usetikzlibrary{pgfplots.external}
\usepackage{graphicx}
\usepackage{epstopdf}
\usetikzlibrary{spy}
\tikzset{mark size=3}
\begin{document}
\pgfplotsset{ tick label style={font=\Large,color=black}, label style={font=\Large,color=black}, legend style={font=\Large},yticklabel style={/pgf/number format/fixed,/pgf/number format/precision=3}}
\pgfplotsset{every axis/.append style={  thick,tick style={ thick},color=black}}
\pgfplotsset{/pgfplots/error bars/error bar style={ thick}}
\pgfplotsset{/pgfplots/every axis x label/.append style={font=\Large,anchor=north}}
\pgfplotsset{/pgfplots/every axis y label/.append style={font=\Large,anchor=near ticklabel}}
\begin{tikzpicture}
\begin{axis}[y tick label style={/pgf/number format/.cd,fixed,fixed zerofill,precision=2,/tikz/.cd},
scaled ticks=false,xlabel={$x$},ylabel=$y$,xmin=0,xmax=1,
y label style={at={(axis description cs:-0.05,0.5)}}]
\addplot+[error bars/.cd,y dir=both,y explicit,] [only marks,mark=o,black] table [x=x,y=y] {Daten.txt};
\addplot [dotted,black] table [x=x_Daten_Linie,y=y_Daten] {Daten.txt};
\end{axis}
\end{tikzpicture}
\end{document}

My question is: How can I apply this, Except the 0 ? i.e. I don't want 0.00 when I got 2 decimal places. Just "0".

Thank you :)
