I think it depends. You are technically allowed to travel at exactly the indicated speed (so the check would technically be ⩽ 80), but due to the nature of real numbers it’s also impossible to physically do. So in the most pedantic sense you must drive at less than 80 km/h and the requirement might as well be < 80.
