Does anybody know how to use
such routines as printf("%.2f") in PASCAL?
I believe Format() is restricted ?!
var x : double;
x := 1.2345;
writeln(x:0:2); { 0 is the total # of chars (if non-zero, aligns right), 2 is the # of decimal places }
Thanks, but that's exactly what I'am doing...
BTW, I figured out one more thing. Code:
x:= 130.125;
writeln(x:0:2);
gives 130.13 if compiled with Delphi (my native compiler)
but gives 130.12 if compiled with FreePascal
So, what I see is not what I get
Will try to get AC...

FINALLY...
Thanks to misof, Cho and little joey.
My mistake was pretty stuppid:
while reading vertexes of polygon I assumed
that some of them might be on one line and
tried to delete useless vertexes "on the fly", but I did it not properly.

My output for Cho's test data (I just talk about the valid ones in his test input) is a little different with Misof's, some of them are 0.01 more than Misof's. Maybe my algorithm loses precision. But still I get AC. This means the test input of the online judge is not very strict in precision, I think.

Thanks to pervious people.
Test data you supply are very useful.
Here is test case #27 you metioned:
Code: Select all
9
18 2
19 18
14 19
6 19
3 18
2 7
2 6
15 2
7 1
1
3 6
Here is output:
I made mistake about array manipulation. (I just forgot to mod N somewhere)
This test data should verify that.
Hope this helps.

Yes. My output for Cho's test data is also a little different.
But i got AC too.

Can anybody help me on this problem?
I have tried every i/o posted in this forum & passed them all.
I can't find any error in my codes.
Can any one give me some test cases?
