[TCLCORE] unsigned integers in TCL

[Ernesto B. <eb...@pe...>]

Hi!

I would be able to work with unsigned integers (IP adresses) on TCL,
using the expr or other functions on it. Currently this doesn't work, 
if my integer is larger than an signed integer, it gets negative:

  ernst@milka:/u/ernst > tclsh8.2
  % expr 3585808128 + 1
  -709159167

Will this be enhanced in TCL 8.4?  Would be great! :)

I now have to use the float to make calculations, and then split on 
the "." and lindex 0, because:

  % expr 3585808128.0 + 1
  3585808129.0
  % expr round(3585808129.0)
  integer value too large to represent

So I have to do this ugly hack:

  % expr 3585808128.0 + 1
  3585808129.0
  % lindex [split 3585808129.0 "."] 0
  3585808129


(Maybe there is another (better) way?).
