现在就知道了标题中的数据类型是什么意思,但是只是只有int相关的类型,没有float相关的类型,我也没有找到相关的头文件,但是我找到了他们分别是怎么类型的了,如下:

typedef float float32_t;
typedef long double        float64_t;
typedef long double        float128_t;

所以,只要加入这两个typedef就可以了。
还有就是,float64_tfloat128_t我找到的类型解释都是long double,我也觉得很奇怪,如果有知道的小伙伴可以在评论区留言。

float和uint8_t是两种不同的数据类型float是单精度浮点数类型,用于表示带有小数部分的实数。它在内存中占用4个字节,可以表示较大的数值范围和较高的精度。 而uint8_t是无符号8位整数类型,用于表示范围在0到255之间的整数。它在内存中占用1个字节,不能表示负数。uint8_t实际上是一个char类型,所以输出uint8_t类型的变量时,实际上输出的是对应的字符,而不是数值。 总结来说,float适用于需要表示小数的情况,而uint8_t适用于需要表示范围在0到255之间的整数的情况。它们在内存占用和数值范围上也有所不同。<span class="em">1</span><span class="em">2</span><span class="em">3</span> #### 引用[.reference_title] - *1* *3* [uint8_t、uint16_t、uint32_t、uint64_t](https://blog.csdn.net/qq_44915792/article/details/124759521)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 50%"] - *2* [c++数据类型之uint8_t/uint16_t/uint32_t/float128_t](https://blog.csdn.net/weixin_50749380/article/details/124014096)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 50%"] [ .reference_list ]
