1、S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
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。S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
2、S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
数字修约的进舍规则S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ

S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
13.2476（1）→13S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
（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）S€è}sâчïbbs.3c3t.com·áêní¾ÆÁ
