数字修约的规则þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç
1、þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç
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。þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç

数字修约的进舍规则þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç
1)拟舍弃数字最左一位数小于5时,则舍去,即45入。þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç

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1þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç

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。þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç

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þÝw¥~áý–ò;bbs.3c3t.comîÅñÞĊç
