Dear ROOT exprets,

I have trouble with long long.
I tried to execute the following script

///// source --------------------------------------

void test(void){

   for(int i=0; i<10; i++){

     long long data;
     data=43000LL;      //  <----- !!!! here !!!!
     cout << i << " : " << data << endl;

   }

   return;
}

---

the results are the following

///// result -----------------------------------------------

root [0] .x test.C

0 : 43000
1 : 167797363
2 : 167797363
3 : 167797363
4 : 167797363
5 : 167797363
6 : 167797363
7 : 167797363
8 : 167797363
9 : 167797363

but what i expect is, of course, the following.

///// ( expected )result -----------------------------------------------

root [0] .x test.C

0 : 43000
1 : 43000
2 : 43000
3 : 43000
4 : 43000
5 : 43000
6 : 43000
7 : 43000
8 : 43000
9 : 43000
