Hello all,
I would like to follow up my previous mail because anyone
seems not to have an interest in this kind of Mathematica bug.
The output of following expressions are self-explanatory:
Sum[1,{i,10}]
> 10
Sum[1,{1000000}]
> 1000000 OK.
Sum[1,{1000001}]
> Sum[1,{1000001}] What?
Sum[1,{i,1000001}]
> 1000001 Yes, it's good. But, ....
Sum[Print@1; Random[],{i,3}]
>
1
1
1
1.52163
Sum[Print@1; Random[],{i,1000001}]
>
1 Only one line printed!!! Something
wrong.
236974.
Product[1,{i,10}]
> 1
Product[1,{i,1000000}]
> 1
Product[1,{i,1000001}]
> StandardForm[Product[1,{i,1000001}]] ????
These outputs are produced in Mathemtatica ver5.0 and ver5.01.
Thank you for your help.
