21 de fev. de 2023 · When x is -0, or -0.5 ≤ x < 0, Math.round (x) returns -0, while Math.floor (x + 0.5) returns 0. However, neglecting that difference and potential precision errors, Math.round (x) and Math.floor (x + 0.5) are generally equivalent. Because round () is a static method of Math, you always use it as Math.round (), rather than as a method of a Math .
