Second test is incorrect.
Quoting:
"The first line contains real numbers A and B (-10000 <= A,B <= 10000) with a two fractional digits precision."
Thus, we can ignore other digits, and if A = 11.0001 we can assume that A = 11.00.
But second test is
11.0001 19
10000
and correct answer is
120.00
6 9
But if number A has two fractional digits precision, then we can ignore other digits. It will be:
11.00 19.00
10000
and correct answer is
120.00
5 9
which checker doesn't accept.
