DESCRIPTION
STEPS TO REPRODUCE
1. calculate factor(any number)
2.
3.
OBSERVED RESULT
For example on Maxima, factor(42) gives:
(%i1) factor(42);
(%o1) 2*3*7
However on Cantor it shows
factor(42)
237
EXPECTED RESULT
2 3 7
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.7.0
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 7.0.12-arch1-1 (64-bit)
Graphics Platform: Wayland
ADDITIONAL INFORMATION
The bug is likely caused by this:
Maxima outputs the list of factors with spaces, as in:
(%i1) factor(42);
(%o1) 2 3 7
and even on a GUI (like wxmaxima) the answer is "2 3 7"
but Cantor makes the answer into latex, and so, the intraspaces are removed,
and the output becomes "237" which is wrong.
Strangely enough, if I "copy and paste" the output from cantor, I get:
$$2\*3\*7$$
so Cantor knows it's a product, and it knows should render the operation, but
"on the screen" it looks as 237 instead of 2 3 7.
Consider for example "factor(439)" it gives as answer: 31113 which is
definitely wrong.
