In release 8.0.0, we support float16_t and bfloat16_t (thanks @dalle). We have reasonable testing and our code is based on an implementation publicly available since GCC 13 (thanks @jakubjelinek for providing support). However issues rem...

operator<<(std::float128_t)是可选的\n 不保证存在operator<<扩展浮点类型的任何重载。<stdfloat>因为std::float128_t情况并非如此,这是很常见的。\n在 x86_64 上:\n \n long double通常是 80 位浮点类型,并且\n std::float128_t是四倍精度 IEEE-754 浮点类型。\n\n 这意味着1)std::float128_t...
在C语言中，结构体变量std1的每个成员占用的内存字节数如下：char ch; 占1个字节 int a[2]; 占4个字节，因为int类型通常占用4个字节，这里包含两个int float t; 占4个字节 double f; 占8个字节 因此，std1的总内存占用为1+4+4+8=17个字节 值得注意的是，实际内存占用可能会因编译器和平台...
char ch;占1个字节 int a[2];占4个字节 float t;占4个字节 double f;占8个字节 1+4+4+8=17char 占一个字节，int每一个元素占两个字节，此处有两个元素所以int类型的数据占四个字节，float型占四个字节，double占八个字节；所以字节数=1+2*2+4+8所以是17个字节；结构体对齐规则:1.第...
