由于uint64_t是unsigned long long的别名,可以直接使用std::to_string进行转换。 下面是一个示例代码,展示了如何将uint64_t类型转换为std::string: cpp #include <iostream> #include <string> int main() { uint64_t number = 123456789012345ULL; std::string str = std::to_string(number...

我有一个保存在 std::string 中的十六进制 MAC 地址。将该 MAC 地址转换为 uint64_t 中保存的整数类型的最佳方法是什么? 我知道 stringstream、sprintf、atoi 等。我实际上用前 2 个函数编写了一些转换函数,但它们似乎比我想要的更草率。 那么,有人可以告诉我一个好的,干净的转换方式吗 std::string mac = ...

所以解决办法也很简单:让后端将其返回的 number 类型转换为 string 即可。...0.30000000000000004 通过上面一步一步计算可以看出,之所以0.1+0.2 === 0.30000000000000004有三个原因: 1)javascript 的数值计算是将数字转换为二进制进行计算的...经过一番精度截取之后再计算就导致了 0.1+0.2 != 0.3 了。五、总结精度...
