Hello, I have a question about whether there is a way around the following problem. If I take different linear combinations of the same vector I should get the same vector as a result. However, applying the linear combination adds some almost-0 error which then implies that the two are not the same…

it’s expected, it’s Float number precision, you should use \approx
