关于精度的计算单精度8位阶码，1位符号，剩下23位尾数，算出2的负23次方，得到0.00000011920928955078125前面0有多少个，就表示能精确到那一位，所以精度为6提供七位有效数字双精度11位阶码，1位符号，剩下52位尾数，算出2的负52次方，得到0.00000000000000022204460492503130808472633361816所以精度为15，提供1...
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...
int main() { printf("The maximum value of float = %.10e\n", FLT_MAX); printf("The minimum value of float = %.10e\n", FLT_MIN); printf("The number of digits in the number = %.10e\n", FLT_MANT_DIG); } 让我们编译和运行上面的程序,这将产生下列结果: The maximum value of ...
