what is the best way to handle big integers in expr command. we know wide in expr.
+4
A:
As of Tcl 8.5, integers are now Bignums (arbitrary precision)
If you're using an older version (which you've said you are, 8.4.x), you'll need to consider what you need to use the numbers for. Most of the standard commands won't accept Bignums, since it hadn't been added to the core at that time. However, if you're just doing math with them, you might want to take a look at
- the tcllib package, which has a library for arbitrary precision math, or
- the mexpr package.
Lastly, it's worth searching the Tclers Wiki for other options.

Sorry... I am working on tcl library for geometrical problems, e.g. finding intersection of geometrical objects. I many cases I need to handle domain errors thrown by expr command. I am thinking to shift on c++. before I just wanted to confirm what I am doing...
