Look up CINT, CDBL, FIX in the KiXtart Manual.
code:
$x = cdbl('389955656444')
$x = 389955656444.0
$x = $x + 355658985665.0
? $x
?

there has also been a long discussion on integer/doubles/floats and variable type precedences a couple of months ago. Please use the KiXtart BBS search to retrieve that topic.
