Text Formatting ⇒ Definition of non-trivial numerical Values (again)

[svend_tveskaeg]

Hi all.

The following MWE is inspired by Clemens' answer in this thread.

Well, here is the test code:

Code: Select all

\documentclass{article}

\usepackage{auto-pst-pdf,pstricks-add}
\usepackage[locale=DE,round-mode=places,round-precision=1]{siunitx}
\usepackage{expl3}

\ExplSyntaxOn
\cs_new_eq:NN \calculate \fp_eval:n
\ExplSyntaxOff

\begin{document}

\begin{figure}
\def\factor{1.2 }
\def\Cx{0 }
\def\Cy{0 }
\def\Bx{\Cx 11.5 \factor mul add }
\def\By{\Cy }
\def\Ax{\Cx 11.63521739130435 \factor mul add }
\def\Ay{\Cy 5.798423601039239 \factor mul add }
\def\Dx{\Cx 0.705044815592284 \factor mul add }
\def\Dy{\Cy 9.373521846563673 \factor mul add }
\def\CD{\calculate{((\Cx-\Dx)^2+(\Cy-\Dy)^2)^(1/2)}}
 \centering
  \begin{pspicture}(14,11.25)
  \psset{unit=0.8cm,nrot=:U}
   \pnode(!\Ax \Ay){A}
   \pnode(!\Bx \By){B}
   \pnode(!\Cx \Cy){C}
   \pnode(!\Dx \Dy){D}
   \pspolygon(A)(B)(C)(D)
   \uput{3pt}[60](A){$A$}
   \uput{3pt}[315](B){$B$}
   \uput{3pt}[225](C){$C$}
   \uput{3pt}[135](D){$D$}
   \pcline{-}(C)(A)
   \naput{\SI{13.0}{\cm}}
   \pcline{-}(C)(D)
   \naput{\SI{\CD}{\cm}}
   \pcline{-}(D)(A)
   \naput{\SI{11.5}{\cm}}
   \pcline{-}(C)(B)
   \naput{\SI{11.5}{\cm}}
   \pcline{-}(B)(A)
   \naput{\SI{5.8}{\cm}}
  \end{pspicture}
\end{figure}

\end{document}

Why in the number in \SI at the node \naput between the nodes C and D printed as 0? I cannot understand why my definition of \CD is wrong.

Thank you in advance!

You're mixing two ways of calculating. I would either use l3fp or the postscript way.

You're mixing two ways of calculating.

Good point! I will remember this.

But... then why is the following not working?

Code: Select all

\documentclass{article}

\usepackage{auto-pst-pdf,pstricks-add}
\usepackage[locale=DE,round-mode=places,round-precision=1]{siunitx}
\usepackage{expl3}

\ExplSyntaxOff

\begin{document}

\begin{figure}
\def\factor{1.2 }
\def\Cx{0 }
\def\Cy{0 }
\def\Bx{\calculate{\Cx+11.5*\factor}}
\def\By{\Cy }
\def\Ax{\calculate{\Cx+11.63521739130435*\factor}}
\def\Ay{\calculate{\Cy+5.798423601039239*\factor}}
\def\Dx{\calculate{\Cx+0.705044815592284*\factor}}
\def\Dy{\calculate{\Cy+9.373521846563673*\factor}}
\def\CD{\calculate{((\Cx-\Dx)^2+(\Cy-\Dy)^2)^(1/2)}}
 \centering
  \begin{pspicture}(14,11.25)
  \psset{unit=0.8cm,nrot=:U}
   \pnode(!\Ax \Ay){A}
   \pnode(!\Bx \By){B}
   \pnode(!\Cx \Cy){C}
   \pnode(!\Dx \Dy){D}
   \pspolygon(A)(B)(C)(D)
   \uput{3pt}[60](A){$A$}
   \uput{3pt}[315](B){$B$}
   \uput{3pt}[225](C){$C$}
   \uput{3pt}[135](D){$D$}
   \pcline{-}(C)(A)
   \naput{\SI{13.0}{\cm}}
   \pcline{-}(C)(D)
   \naput{\SI{\CD}{\cm}}
   \pcline{-}(D)(A)
   \naput{\SI{11.5}{\cm}}
   \pcline{-}(C)(B)
   \naput{\SI{11.5}{\cm}}
   \pcline{-}(B)(A)
   \naput{\SI{5.8}{\cm}}
  \end{pspicture}
\end{figure}

\end{document}

Now, nothing is printed at all.

I am now sticking to one type of notation (I think).

[cgnieder]

I don't really know... are you sure about the scaling? It seems to print everything at nearly the same place. The calculations are working:

Code: Select all

\documentclass{article}
\usepackage{expl3}

\ExplSyntaxOn
\cs_new_eq:NN \calculate \fp_eval:n
\ExplSyntaxOff

\begin{document}


\ttfamily\noindent
\def\factor{1.2 }%
\def\Cx{0 }%
\def\Cy{0 }%
\def\Bx{\calculate{\Cx+11.5*\factor}}Bx: \Bx \\
\def\By{\Cy}By: \By \\
\def\Ax{\calculate{\Cx+11.63521739130435*\factor}}Ax: \Ax \\
\def\Ay{\calculate{\Cy+5.798423601039239*\factor}}Ay: \Ay \\
\def\Dx{\calculate{\Cx+0.705044815592284*\factor}}Dx: \Dx \\
\def\Dy{\calculate{\Cy+9.373521846563673*\factor}}Dy: \Dy \\
\def\CD{\calculate{((\Cx-\Dx)^2+(\Cy-\Dy)^2)^(1/2)}}CD: \CD

\end{document}

The scaling is for something else; not related to this.

When I compile the following MWE, the values are (of course) printed, but the PS figure is not.

I have attached the log file.

Is the figure printed when you compile?

[CrazyHorse]

The scaling is for something else; not related to this.

the spaces are missing:

You are kidding me. How blind can one be.

Thank you to both of you for helping me!
