minus-square@[email protected]linkfedilink6•10 months ago0.999… = 1 in theory also. Otherwise, there exists a δ such that 1 - δ = 0.999… Then, the δ should have a first nonzero digit. Let us say it is in the millionth placd. But then, 0.999… cannot have a 9 in the millionth place.
minus-square@matiamaslink2•10 months agoEven in theoretical math, 0.999 repeating ends up being exactly equal to 1. In fact, any terminating decimal can be rewritten in a similar manner. For example, 0.25 is exactly equal to 0.24999999 repeating
