上取整 四舍五入 下取整
Sorry, something went wrong.
Math.ceil() 函数返回大于或等于一个给定数字的最小整数。 `console.log(Math.ceil(.95)); // expected output: 1
console.log(Math.ceil(4)); // expected output: 4
console.log(Math.ceil(7.004)); // expected output: 8
console.log(Math.ceil(-7.004)); // expected output: -7 ` Math.round() 函数返回一个数字四舍五入后最接近的整数。
Math.floor() 返回小于或等于一个给定数字的最大整数。
