浮点转字符串
浮点型转换为字符串可以使用标准库函数sprintf(),该函数可以将浮点数格式化为字符串。具体使用方法如下:
```c
float num = 3.14;
char str提到了在单片机开发中常用的字符串相关函数,包括将数字转换为字符串的功能。所以你可以根据引用中提到的方法,将浮点型数值先转换成整型数值,然后再将整型数值转换成字符串。
```c
float num = 3.14;
int intNum = (int)num; // 将浮点型转换为整型
char str中提到的atof()函数进行字符串到浮点数的转换。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
