C4244 也可在等级 3 和等级 4 触发;有关详细信息,请参阅编译器警告(等级 3 和等级 4)C4244。 示例 下面的示例生成 C4244: C++ // C4244_level2.cpp// compile with: /W2intf(intx){return0; }intmain(){doublex =10.1;inti =10;return(f(x));// C4244// try the following line instead/...

double型精度比float精度高，编译器默认生成或运算的小数都是double型 警告的意思都是由double转换到float时可能会有精度损失，只是警告 建议所有float都使用double型数据 当然如果确信自己的运算都在精度范围内，可以忽略这个警告。
