Function AlmostEqualRel

libs/base/math.hpp:72–75

// The same considerations as in AlmostEqualAbs apply.
template <typename Float>
bool AlmostEqualRel(Float x, Float y, Float eps)
{
  return fabs(x - y) < eps * std::max(fabs(x), fabs(y));
}

// Returns true if x and y are equal up to the absolute or relative difference eps.
