CarmSqrt.cpp 三种 浮点数开平方数精度对比

carmSqrt 方法开发浮点数对比系统自带 三种对比精度 39 int main(){ 40 float in = 237.0f; 41 42 float out1 = CarmSqrt(500.0*500.0); 43 float out2 = invSqrt(500.0*500.0); 44 float out3 = sqrt(500.0*500.0); 45 46 std::cout << "out1: " << out1 << ", out2: " << out2 << ", out3: " << out3 << std::endl; 47 48 return 0; 49 }
