PStricks problem

[Arek Kuźniewski]

I need to define function (in pstricks mode) for drawing lines. Function
should work like this:
------------
\def\newhline(#1,#2){#3}{\psline(#1,#2)(#1+#3,#2)
------------
Of course this function doesn't work.
How can I define this function? If I needed only integer values of #1
and #3, I would do it by counters, for example:
------------
\newcounter{nhlc}
\def\newhline(#1,#2){#3}{\setcounter{nhlc}{#1}\stepcounter{nhlc}{#3}
\psline(#1,#2)(\thenhlc,#2)}
-------------
But the problem is, that I need #1 and #3 in real (e.g. #1=1.2 and #3=4.3).
The second definition doesn't work for it.

Is some way to define function for calculation #1+#3?

Hello,

Have a look at the calc package! It brings changes to the arguments and
lengths of the counters.
I had the same problem when I created the pst-soroban package. (Have a
look to pst-soroban.sty-CTAN)

Hope this helped.

Hello

I can't see where are you making operation on non-integer values in your
pts-soroban.sty

You always have A+B or A-B or A*B, but A and B are always integer (1, 2,
3, ...). I need to do these operations on real A and B (1.2, 1.3, 1.25
etc.).
If I'm wrong, tell me, where (in your pst-soroban.sty) you can make
+/-/* operations on the real values.

(I hope my description is clear, because my English is not good).

Greetings,
Arek

Hi!

You are right for pst-soroban.
Here is the beginning of pgf-soroban where there is computation of new
lengths with decimals in the \ladj command (lengthadjust):
the argument of \ladj is a decimal asking for a drawing a
fraction/multiple of the normal (unit??) one, which draws a soroban of
the actual size.
(I think what you need is decimal lengths??)

Hope this helps.
