误差误差error数据的近似值与准确值的差异。衡量数据可靠性和精确度的重要方面。求解一个具体问题，一般首先要将问题的条件简化，然后建立一个数学模型，再应用某种合理的算法求出模型问题的数值结果。这些最后求得的结果往往只是原先问题准确解的近似，两者间的差异就是误差。样本平均与总体平均之差是误差的最普遍的例子。近似值与准确值之差称作误差或绝对误差，而绝对误差与准确值之比称为相对误差。百分比误差是相对误差的百分比表示。绝对误差和相对误差的上界分别称作绝对误差界和相对误差界。这些概念表达了近似值的精确程度。造成误差的原因是多方面的，除了人为原因外，主要有以下4个方面的来源：①由于模型的局限与近似造成的误差称为模型误差。②由于观测工具不准确和随机因素干扰引起的误差叫做观测误差。③由于简化数学计算，用近似表达式代替精确表达式引起的误差称为截断误差。④由于计算机字长的限制，把位数较多的数用位数较少的数代替(通常用四舍五入法则)，由此产生的误差称作舍入误差。
