Inconsistency in C++ STL sqrt function
Submission 1 : AC
Submission 2 : WA
The only difference between Submission 1 and Submission 2 is that, in Submission 1 I'm using a self made square root function, while in Submission 2, I'm using the C++ STL sqrt function, otherwise everything else is identical. Should it be considered as an inconsistency in C++ STL sqrt function? If not, why?
