Category: Lisp Core - Plotting Group: None >Status: Pending >Resolution: Works For Me Priority: 5 Private: No Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: plot2d number overflow Initial Comment: plot2d(1.0e9,[x,0,1]) gives the pop-up error "Error: integer value too large to represent". "Details" shown below. It also doesn't recover well from the error -- it shows an empty plot window (in Plot Windows: Separate mode). Maxima version: 5.9.0 Maxima build date: 19:10 2/9/2003 host type: i686-pc-mingw32 lisp-implementation-type: Kyoto Common Lisp lisp-implementation-version: GCL-2-5.0 integer value too large to represent integer value too large to represent while executing "expr {round(ceil($aa)) }" (procedure "getTicks" line 12) invoked from within "getTicks $y2 $y1 [expr {$shei/50}" (procedure "axisTicks" line 27) invoked from within "axisTicks $win $c" (procedure "replot2d" line 40) invoked from within "replot2d $win" (procedure "plot2d" line 4) invoked from within "plot2d -data {plot2d {label "1.0E+9"} {xversusy { 0.0000000000 0.0100000000 0.0200000000 0.0300000000 0.0400000000 0.0500000000 0.0600000000 0...."

I have tried the plot with openmath plot format with SBCL 1.0.29/Linux and GCL 2.6.8/Windows. In both cases the plot window shows a horizontal line. Setting the status to pending and the resolution to "works for me".

Tcl/tk is barfing because the argument of round is a float which is too big to fit into a 32 bit int. Looking at the code for getTicks (plotting/omplotdata), I don't see any easy way to fix it. Maybe we can use 64 bit ints or something. Here is an observation of the bug: set_plot_option([plot_format,openmath]); plot2d(1.0e9,[x,0,1]); => Error in startup script: integer value too large to represent while executing "expr {round(ceil($aa)) }" (procedure "getTicks" line 12) invoked from within [...] With gnuplot, plot2d succeeds and the plot window shows a horizontal line. ---------------------------------------------------------------------- Comment By: Raymond Toy (rtoy) Date: 2003-05-25 16:14 Message: Logged In: YES user_id=28849 This seems to be an issue with tcl/tk. With gnuplot, a straight line is plotted. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=695086&group_id=4933 |
