数字修约的规则$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
1、$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
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。$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
2、$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
数字修约的进舍规则$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
1)拟舍弃数字最左一位数小于5时,则舍去,即45入。$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
例如:13.24760.1)→13.2$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®

13.2476
1)→13$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
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1$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
例如:1167100)→1200$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®

1)→11$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
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。$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
例如:2.0500.1)→2.0$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®

4)负数修约同前$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
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2$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®

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$9^qa,Ñ9Þbbs.3c3t.comÂ'µRʱ4M®
