Give your answer to the nearest 0.05
请问这个是怎么近似?
如果是三位及以上小数是先四舍五入到2位小数,然后看第二位小数是接近5还是0,取最接近的?
如果是二位,则直接看第二位小数是接近5还是0,然后取最接近的?
如果一位,则后面补0,补到第二位?
是这这样吗?
那比如:
7.126->7.13->7.15?
7.116->7.12->7.10?
7.18->7.20?
7.17->7.15?
7.1->7.10?
For 7.126, which is between 7.10 and 7.15, it is closer to 7.15, so it's rounded up to 7.15.
Whereas for 7.116, it's closer to 7.10, so it's rounded to 7.10.
