关于c : maximum float x 是否定义了行为? Is maximum float + x defined behavior? 我使用以下方法进行了快速测试: floatx=std::numeric_limits<float>::max();x+=0.1; 结果是 x == std::numeric_limits::max() 所以它没有超过限制。 不过,这是否保证跨编译器和平台的行为? HLSL 呢? 相关讨论 Is t...
[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...
