I did some test with the long math elements, too
code:
? @KIX

; this is a number KiXtart cannot handle as integer
$e=44680832201
? '$$e='+$e

$t=10
? '$$t='+$t

$d=0+$e/$t
? '$$d=0+$$e/$$t='+$d

$d=0.+$e/$t
? '$$d=0.+$$e/$$t='+$d

$e=44680832201.
? '$$e='+$e

$d=0+$e/$t
? '$$d=0+$$e/$$t='+$d

$d=0.+$e/$t
? '$$d=0.+$$e/$$t='+$d

gives an output of
code:
4.10 Release Candidate 2
$e=1731159241
$t=10
$d=0+$e/$t=173115924
$d=0.+$e/$t=173115924
$e=44680832201
$d=0+$e/$t=0
$d=0.+$e/$t=4468083220.1

The first time $e gets misassigned because Kixtart cannot handle an integer that large. But, what happens int he next to last $d calculation? It should definitely not be '0'?
