C and Pascal

There are 2 same solutions (C, Pascal).

C solution gets WA, 9

Pascal solution gets AC

Why??? Please, give me some hints about it.

I think it's precision problems )

For example (sizeof(long double) == 8)

Re: I think it's precision problems )

I thought it's so only in Visual C.

GNU C and Borland C compilers use sizeof(long double) = 10.

Am I right?

Re: I think it's precision problems )

Yes.

But as far as I know Intel C++ compiler is used there. And in ICL (at least in 8.1) sizeof(long double)==8

This problem suppose using of long arithmetics (-)

Re: This problem suppose using of long arithmetics (-)

Of course!

But solution without it is more short and beauty. :)

And it's more interesting to solve problem

using only Extended.

But if juri suppose exact numbers

when answer is unequivocal it would be funny

try adjust eps-heuristics. Next time you would be killed by

rejujement.

I have Ac using 120-digits integers and dot-product as angle haracteristics. Thus use only +,-,*,<,==.

Re: This problem suppose using of long arithmetics (-)

My program doesn't use any long arithmetics - only standard Pascal's real (or extended?) type, and it hasn't any problem with accepting this problem. If jury assumed using long arithmetics, then testset is very weak...

Could anybody say me how find point, symmetrical to given point relatively some line?

Without division...

Thanks
