Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Satoshi Adachi (satoshi_adachi) Assigned to: Nobody/Anonymous (nobody) Summary: 2D display of long denominator of nested fractional Initial Comment: Dear Developers of Maxima, I think that I met a bug of Maxima to display nested fractionals in the 2D style. If the denominator of a nested fractional is long, it is not displayed correctly. The display width controll based on the variable LINEL seems to be not effective in the denominator. Compared to this, the numerator of a nested fractional causes no such problem to be displayed even when the numerator is long. Here, I have prepared a program for demonstration:  /* * denominator_of_nested_fractional_is_not_displayed_correctly.maxima: * * The line length, which is usually controlled by the variable LINEL, * is not recognized in the denominator of a nested fractional, if the * nested fractional has a long denominator. * * S.Adachi 2008/04/29 */ /* Do not use ``display2d:false;'', since this is a problem in displaying a mathematical expression in the 2D style. */ X:product(f(i+1/2),i,0,20); Y:product(g(i+1/2),i,0,20); Z:X/Y; /* A nested fractional; its denominator is not displayed correctly. */ /* END */  This is a problem in displaying mathematical expressions in the 2D style. Accordingly, I cannot attach here the log list that is obtained by running the above program. (If I include in a bug report the mathematical expressions that are displayed in the 2D style by Maxima, the posted bug report becomes a disordered gabage in appearance.) So, please execute the above program by the command maxima b denominator_of_nested_fractional_is_not_displayed_correctly.maxima to see the phenomenon that I am reporting in this letter. I am using a console terminal with line width 80 to run the above program. It is essential for Maxima to display any mathematical expression in a correct mannar. If it is not, we cannot read the output from Maxima. So, please fix this bug.

The example I have given in the bug report ID:635708 is a more simple example for the reported problem in this bug report. But there are two problems and this bug report is not related to the first one. The problem of this bug report is present until Maxima 5.15. In Maxima 5.14 the display of this example is correct.

Dieter Kaiser  Comment By: Dieter Kaiser (crategus) Date: 20100203 01:04 Message: I had again a look at this problem. The example I have given in the bug report ID:635708 is a more simple example for the reported problem in this bug report. But there are two problems and this bug report is not related to the first one. The problem of this bug report is present until Maxima 5.15. In Maxima 5.14 the display of this example is correct. The example I have given in the report ID:635708 is correct in Maxima 5.14 too, but not since Maxima 5.15. This is again the more simple example: We take a long numerator and a long denominator. (%i1) num:a1+a2+a3+a4+a5+a6+a7+a8+a9; (%o1) a9 + a8 + a7 + a6 + a5 + a4 + a3 + a2 + a1 (%i2) denom:b1+b2+b3+b4+b5+b6+b7+b8+b9; (%o2) b9 + b8 + b7 + b6 + b5 + b4 + b3 + b2 + b1 We set linel to a small value 10. (%i4) linel:10; (%o4) 10 We display num/denom. This is a correct display. (%i5) num/denom; (%o5) (a9 + a8 + a7 + a6 + a5 + a4 + a3 + a2 + a1) /(b9 + b8 + b7 + b6 + b5 + b4 + b3 + b2 + b1) We get the error when we multiply the denominator with a further constant. The last line is no longer broken up correctly: (%i6) num/(x*denom); (%o6) (a9 + a8 + a7 + a6 + a5 + a4 + a3 + a2 + a1) /((b9 + b8 + b7 + b6 + b5 + b4 + b3 + b2 + b1) x) Dieter Kaiser  Comment By: Dieter Kaiser (crategus) Date: 20100202 17:40 Message: I think this bug report is related to the following bug report: ID 635708  Bad 2ddisplay of a long denominator. A 2ddisplay with a small value of linel shows that the long denominator is not broken up correctly. This seems to be a general problem.

I can try some different versions, but it will be a while. The line width doesn't appear to be important  I get incorrect output when linel:65, or linel:70, or linel:80.
