数字修约的规则5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
1、5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
修约间隔:指确定修约保留位数的一种方式,修约间隔一旦确定后,修约值即为该值的整倍数。5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
2、5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
数字修约的进舍规则5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
1)拟舍弃数字最左一位数小于5时,则舍去,即45入。5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
例如:13.24760.1)→13.25 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k

13.2476
1)→135 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
2)拟舍弃数字最左一位数≥5时,而且后面的数字并非全部为0时,则进1,(保留末位数加15 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
例如:1167100)→12005 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
12*102

10.502
1)→115 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
3)似舍弃数字最左一位数为5,而后面无数字或全部为0时,若所保留的末位数为奇数(13579)则进一,为偶数(24680)则舍弃,即奇进偶不进。5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
例如:2.0500.1)→2.05 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k

0.0345
(保留2位有效)0.0345 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
4)负数修约同前5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
50.5单位修约时,将拟修约数乘以2,按指定数位依进舍规则修约,所得数值再除以25 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k

一些例子编排变形了,,应该是A,2A,2A(1),A的修约值。。其它类推,看得懂的就看吧,大致意思还是清楚5 ýnϧ¿ùzbbs.3c3t.comÊh?@¢mø=k
