Dear Bug Team!
string-to-int sometimes returns unsightly values which makes
writing elisp functions that operate on tables of numbers
very complicated if you want them to remain easy on the eyes.
I'm not sure where the problem is: xemacs, os, compiler, cpu???
Any help would be appreciated:
(string-to-int "8.180E-1")
0.8179999999999999
Interestingly, on my windows native XEmacs (both 21.4 and 21.5),
compiled with Visual C++, I get:
(string-to-int "8.180E-1")
0.818
On my Cygwin XEmacs (both 21.4 and 21.5), compiled with gcc, I get:
(string-to-int "8.180E-1")
0.8179999999999999
HTH,
Vin
