SQL FLOAT TO INT MYSQL: CAST(float_value AS SIGNED INTEGER) 1. SQL SERVER: ROUND(float_value , lenth) 1. lenth:小数点后面保留长度;结果四舍五入;
int speed1 = (int)(6.2f * 10);float tmp = 6.2f * 10;int speed2 = (int)tmp; speed1并且speed2应该具有相同的值,但事实上,我有: speed1 = 61speed2 = 62 我知道我应该使用Math.Round而不是cast,但我想了解为什么值不同。 我查看了生成的字节码,但除了存储和加载外,操作码是相同的。 我也在...

If the value is float, then it is cast to a FLOAT, otherwise not.

intintValue=static_cast<int>(floatValue); Here,floatValueis the float variable we want to convert to an int, andintValueis the resulting integer variable. Let’s demonstrate this through a complete example: #include<iostream>#include<string>#include<vector>using std::cout;using std::endl;usi...
最常见的就是int类型转float或者是float转int,而C++语言默认的自动转型有时候带来意向不到的大BUG。所以最好采用显式的强制转型方式比较好。推荐使用static_cast,它是C++ 中四个命名强制类型转换操作符之一,经常被用于基础数据类型转换,非常好用。 想把输入图像512x512的缩放到300x300,先计算缩放: ...
