Some new tests have been added. 5 authors lost AC.
Sample input #2 (as well as test #2) has been modified, now all triangles in all tests have positive area.

Can this problem be solved with float arithmetics? Or must I use long integer arithmetic?

Yes, this problem can be solved with float arithmetics even without epsilon-precision comparison (but it only because tests at present is enough easy)

Using 'double' type is enough (-)
