NC information
N15 round numbers and measures to an appropriate degree of accuracy (e.g. to a specified number of decimal places or significant figures); use inequality notation to specify simple error intervals due to truncation or rounding
e.g. x = 2.3 correct to 2 s.f. implies that 2.25 ≤ x < 2.35
N16 apply and interpret limits of accuracy including upper and lower bounds
