数字修约的规则ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
1、ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
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。ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
2、ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
数字修约的进舍规则ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
（1）拟舍弃数字最左一位数小于5时，则舍去，即4舍5入。ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
例如：13.2476（0.1）→13.2ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
13.2476（0.01）→13.25ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
13.2476（1）→13ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
（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）ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
例如：1167（100）→1200ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
12*102ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
1167（10）→1170ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
117*10ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
10.502（1）→11ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
（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（1、3、5、7、9）则进一，为偶数（2、4、6、8、0）则舍弃，即奇进偶不进。ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
例如：2.050（0.1）→2.0ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
0.150（0.1）→0.2ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
1350（100）→1400ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
14*102ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
0.0345（保留2位有效）0.034ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
（4）负数修约同前ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
（5）0.5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。ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð

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ü¥ø2Wë²ê“bbs.3c3t.comÊKw›Q…Õð
