摘要
Abstract
This paper introduced the classification of numerical calculation errors, and used math expressions as examples to illustrate truncation error. According to IEEE754 criterion, this paper used math expressions to explain rounding error. Then this paper simply analyzed the truncation error and rounding error. At last, this paper pointed out attentions in the numerical calculation.关键词
