Here are couple other issues encountered with
printf. This time with negative zero-padded
integers.
'%10.10d ' sprintf"_ 0 i:2
00000000-2
00000000-1
0000000000
0000000001
0000000002
'%010d ' sprintf"_ 0 i:2
-2
-1
0
1
2
Compare with C output
printf ("[%-10.10d]"), with 1234, -1234:
[0000001234]
[-0000001234]
printf ("[%010d]"), with 1234, -1234:
[0000001234]
[-000001234]
From
int main(int argc, _TCHAR* argv[]) {
printf("printf (\"%s\"), with %d, %d:\n", "[%-10.10d]", 1234,
-1234);
printf("[%-10.10d]\n[%-10.10d]\n\n", 1234, -1234);
printf("printf (\"%s\"), with %d, %d:\n", "[%010d]", 1234,
-1234);
printf("[%010d]\n[%010d]\n\n", 1234, -1234);
...
}
