数值修约

四舍六入五成**则

数值修约,又称数字修约,是指在进行具体的数字运算前,按照一定的规则确定一致的位数,然后舍去某些数字后面多余的尾数的过程。

数值修约的历史非常古老,甚至可能比除法还要古老。一些美索不达米亚的泥板上有倒数的修约值。圆周率、年月长度的近似值也很古老。现在被广泛使用的数值修约规则,主要有四舍五入规则和四舍六入五留**则。在**尚可见到无条件舍去法、无条件进位法等(高斯符号)。

四舍五入规则是人们习惯采用的一种数字修约规则。

四舍五入规则的具体使用方法是:

在需要保留有效数字的位次后一位,逢五就进,逢四就舍。

例如:将数字2.1875精确保留到千分位(小数点后第三位),因小数点后第四位数字为5,按照此规则,应向前一位进一,所以结果为2.188。同理,将下列数字,全部修约为四位有效数字,结果为:
