Truncating conversionmeans that any fractional part is discarded, so that e.g. 3.9 is converted to 3. Such a conversion is the default floating to integer conversion in C in the sense that it is applied whenever a value of a floating-point type (float, double or long double) is to be ...
1.float a=5.5f; int b=(int)a; 此时输出b等于5,舍去了小数点后面的 2.string a="123"; int b=Convert.Toint32(a); 此时输出b为123 但是如果string a="123.5f"这种不会输出123,会报错 注意这里不是toint而是Toint32,因为内置类型表里是Toint32。比如想将字符串转化为float只能写成 convert.tosingle...

Theround() functionis a built-in function in Python that rounds a number to the nearest value and hence we can convert float to int Python. It can operate on both integers and floating-point numbers. Theround() functionin Pythonrounds a number up if the fractional part is 0.5 or higher ...

C#中数据转换的方法很多,拿将目标对象转换为整型(int)来讲,有四种方法:分别为(int)、int.Parse()、int.TryParse()和Convert.ToInt32() 在我们实际开发项目的过程中,我们碰到需要被转换的类型大概有3大类,分别是空值(NULL)、数字类型(包含float,double,int,long等)和字符串(string)这3类。
(2)对数据进行四舍五入时候的区别 a. Convert.ToInt32(double value) 如果 value 为两个整数中间的数字,则返回二者中的偶数;即 3.5转换为4,4.5 转换为 4,而 5.5 转换为 6。 不过4.6可以转换为5,4.4转换为4 b. int.Parse("4.5") 直接报错:"输入字符串的格式不正确". c. int(4.6) = 4 Int转化其...
