What's your grounds for claiming that?
regards, tom lane
I did something like int128 a1 = 9223372036854775807 + 1;
I also did something like int128 a1 = (int128)9223372036854775807000;
I misread the warning. I should do the cast first.
The second expression has a warning. I guess because
There is no support in GCC for expressing an integer constant of type __int128 for targets with long long integer less than 128 bits wide.
