Disabling scaled x ticks causes "Dimension too large" in pgfplots

Question

I want to change my x axis tick labels to read 0K 20K 40K 60K 80K similar to my y axis tick labels in this chart:

begin{document}
begin{tikzpicture}
begin{axis} [
        ymax=0,
        xticklabel = {
            pgfmathparse{tick/1000}
            pgfmathprintnumber{pgfmathresult},K
        },
%        scaled x ticks=false,
        yticklabel = {
            pgfmathparse{tick/1000}
            pgfmathprintnumber{pgfmathresult},K
        },
        scaled y ticks=false,
    ]
    addplot +[blue,mark=none] table [x=iter, y=prod, col sep=semicolon] {data.csv};
end{axis}
end{tikzpicture}
end{document}

Now when I uncomment the line scaled x ticks=false, I receive this error:

! Dimension too large.
<to be read again> 
                   relax 
l.50     end{axis}

? 
! Emergency stop.
<to be read again> 
                   relax 
l.50     end{axis}

!  ==> Fatal error occurred, no output PDF file produced!

This error message seems to be associated with divisions by zero. Due to my set denominator of 1000 I don’t see how that could the cause. Therefore I have no idea why this method works for the y axis but not for the x axis. Could someone please point out what I’m doing wrong?

Update: axes with scaled ticks=base 10:-3,

Based on BambOo’s suggestion:

pgfplots ticks tikz pgf

oschlueter · Answer

The documentation of pgfmathparse held the answer:

The math engine in pgf typically uses TEX’s internal arithmetics. That means: it is well suited for
  numbers in the range [−16384, 16384] and has a precision of 5 digits
  
  The number range is typically too small for plotting applications. pgfplots improves the number range
  by means of pgfkeys{/pgf/fpu}pgfmathparse{1+41} to activate the “floating point unit” (fpu) and
  to apply all following operations in floating point.

Adding pgfkeys{/pgf/fpu} into my blocks for xticklabel and yticklabel allows for the calculations required to render my axis as I want it to.
