That is not the kind of "bug" you would report here. This bug is in
your usage, not C++.

You used pow(...) (see: https://en.cppreference.com/w/cpp/numeric/math/pow)
pow() takes a floating point number and returns a floating point
you then add it to an integer (truncating the floating point value).
It is a well known fact that floating point numbers do not store exact
values,
conversions to & from other types and/or comparisons with floating point
numbers do not work well.
