#2359 Draw error with draw_realpart=false

[Mikael Samsøe Sørensen]

When trying to plot the example from the documentation in the draw package: http://riotorto.users.sourceforge.net/gnuplot/complex/drawrealpart.html

wxdraw2d(
/* default value */
explicit(sqrt(x^2-4*x)-x, x, -1, 5),
/* set value to false */
color = red,
draw_realpart = false,
explicit(sqrt(x^2-4*x)-x+2, x, -1, 5) )$

I get the error:

Maxima encountered a Lisp error:
Error in SETF [or a callee]: Expected a LONG-FLOAT
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.

Windows version 5.26.0

This bug is fixed in git repository.

You can download files "draw.lisp" and "grcommon.lisp" from there and place them in your local share folder.

Thanks.
