TCL Number error?

[homerjj]

WHy when i run the following command do i get the following error.
"
tcl> expr 20000000000
Error: integer value too large to represent"

But when i use a larger number it works fine.

I don't run into your problem:

% expr 20000000000
20000000000
% expr 20000000000*4
80000000000
%

I'm using Tcl 8.4.5 on Windows 2000.

Thanks
for the reply but i didnt explain it very well.

Here is another example of the inconsistencey

tcl> expr 2147483648
-2147483648

Surely this is wrong and occurs for numbers between 2^31 and 2^-32.

Any ideas as to why this occurs?

Here's another:-

tcl>expr 4294967290
-6

Why?

 

[Bong]

still:

% expr 2147483648
2147483648
% expr 4294967290
4294967290
%
