I'd like to plot the following function between 0 and 0.5 using pgfplots.

However I get as a result the fluctuating line in picture. I'd like to get a smooth line, as the function is.

Is this a numerical approximation error?

Here is a mwe

documentclass[tikz]{standalone}

usepackage{pgfplots}



begin{document}

begin{tikzpicture}

    begin{axis}[axis x line=middle, axis y line=middle,

             width=linewidth, height=0.5linewidth,

             xmin = 0, xmax=0.5]

    addplot[smooth, domain=0:0.5, samples = 100] {

        exp(0.1*x)-sin(deg(0.1*x))

    }; 

    end{axis}

end{tikzpicture}

end{document}

Output:

pgfplots

Yes, these are numerical issues. In what follows I describe two ways to resolve them: using lualatex as compiler or using xfp for the computation. Both of them give smooth results, which agree.

Once I add pgfplotsset{compat=1.16} and compile

documentclass[tikz]{standalone}

usepackage{pgfplots}

pgfplotsset{compat=1.16}

begin{document}

begin{tikzpicture}

    begin{axis}[axis x line=middle, axis y line=middle,

             width=linewidth, height=0.5linewidth,

             xmin = 0, xmax=0.5]

    addplot[smooth, domain=0:0.5, samples = 100] {

        exp(0.1*x)-sin(deg(0.1*x))

    }; 

    end{axis}

end{tikzpicture}

end{document}

with lualatex I get

If you do not want to use lualatex you could employ xfp instead.

documentclass[tikz]{standalone}

usepackage{pgfplots}

%pgfplotsset{compat=1.16}

usepackage{xfp}

begin{document}

begin{tikzpicture}

foreach X [count=Y] in {0,0.005,...,0.5}

{ifnumY=1

xdefLst{(X,fpeval{exp(0.1*X)-sin(0.1*X)})}

else

xdefLst{Lst (X,fpeval{exp(0.1*X)-sin(0.1*X)})}

fi}

    begin{axis}[axis x line=middle, axis y line=middle,

             width=linewidth, height=0.5linewidth,

             xmin = 0, xmax=0.5,ytick=empty]

    addplot[smooth,no marks]  coordinates {Lst}; 

    end{axis}
