| 摘 要: 浮点数是C语言中的一种数据类型，但在标准C中并没有给出其具体的描述，即数的存储格式及表示范 围。部分经典的C语言程序设计教程中给出了浮点数的表示范围，但存在不严谨和值得商榷的地方。结合IEEE754标 准，就C语言中浮点数内在存储格式进行分析并给出结论。 |

| Abstract: The float is a data type in C language,but its in standard C and did not give a specific of description:that is the number of storage format and the scope of representation.Part of classically C language programming tutorial gives a range of floating-point represent,but there is not rigorous and need to discussion.Combined IEEE754 standards,provided analyzation and conclusions in C language in internal storage floating-point format. |
| Keywords: C language floating-point scope of representation |
