数字修约的规则öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò
1、öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò
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。öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò

数字修约的进舍规则öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò
1)拟舍弃数字最左一位数小于5时,则舍去,即45入。öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò

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öź8U{õÐ\Vbbs.3c3t.comhk7Îü*ý’´ò
