What's wrong with my formula?!

Послано Alexey 25 июн 2006 13:59

Readln(n);
Readln(ss); delete(ss,pos('.',ss),1); Val(ss,s,r);
Readln(ss); delete(ss,pos('.',ss),1); Val(ss,l,r);
count:=(s div l)*n+((s mod l)*n) div l+1;

Please...

Precision is main trouble of this problem =)

OK, but I don't Use real types... Can U give me the test to improve my program?

I will try to explain...
When you read real number, for example 1.115, after reading you can get something like 1.11499999, and after custing to integer you'll get 1114 instead 1115. Just try different tests.

But I read String!
