数字修约的规则ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
1、ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
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。ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
2、ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
数字修约的进舍规则ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
1)拟舍弃数字最左一位数小于5时,则舍去,即45入。ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
例如:13.24760.1)→13.2ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É

1)→13ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
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1ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É

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。ÿq¼ Ã H|U:bbs.3c3t.combLØÂÅáB&É
