I was doing this problem: https://codeforces.net/contest/1730/problem/B and I have submitted 3 versions of binary searching on the answer and all of them are failing on test case 3 (wrong answer 36th numbers differ — expected: '40759558.0000000', found: '40759600.0000000', error = '0.0000010') -- all of them produce the same "wrong" answer.

I might be missing something stupidly obvious here but I am actually losing my mind right now. Could someone take a look at what could be going wrong?

In case you do not want to read the problem statement itself:

• Given a bunch of functions of the form f(x) = |x — x_i| + t_i and if we define a new function g(x) as being the max across all the functions at x, we want to find the x value that minimizes g(x).
