I'm sure tests are wrong. Look example here!

I've submitted one 'Accepted Pascal Solution' from forum and
got accepted. Than I started to run my program and that program
on random tests.
After about 100,000 random tests I've noticed the difference.
Example
24.80 24.83
My prg. answered 129
That prg. asnwered 125
But 24.80 / 100 * 125 = 31.0000000000
    24.83 / 100 * 125 = 31.0375000000
      What is the number of conductors?
GREATER than 31 and LESS that 31.0375??
May be GREATER means NOT LESS?

    24.80 / 100 * 129 = 31.992..
    24.83 / 100 * 129 = 32.0307..
And here all is OK.

I got WA,my code also answered 129!!!!

but my program got 125
It's still wrong answer
maybe FRAC funtion must be used

haha
My pascal said that trunc(24.8*100)=2479
I'll use round().

My AC Pascal Pro gives 129.
