The linking number in knot theory is definitively an integer, as it quantifies the number of times two curves wind around each other. This property arises from the fundamental nature of crossings in knot diagrams, where curves can only be in a state of crossing or not crossing. The linking number is calculated using specific techniques in algebraic topology, ensuring that it remains an integer regardless of the configuration of the curves.
