Converting Double to Integer in C# In C#, the double data type is a floating-point type that represents a double-precision 64-bit number (8 bytes). On the other hand, the int data type is an integer type representing a 32-bit signed integer. Converting a double to an integer in C# ...
将System.Double 转换为 System.Int32。 C# 复制 public object? Convert (object value, Type targetType, object parameter, System.Globalization.CultureInfo culture); 参数 value System.Object System.Double 值推断运行时引擎类型。 targetType System.Type 绑定目标属性的类型。 此操作未...
Convert.ToInt32则会进行四舍五入 int.TryParse只能转换整数,即浮点类型全部会返回0 (int)不会进行四舍五入,只取整数部分,小数点部分完全舍弃 usingSystem; publicclassDoubleToInt { publicstaticvoidMain() { Test_DoubleToInt(0.4); Test_DoubleToInt(0.5); Console.ReadKey(); } staticvoidTest_DoubleToI...
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 ...
(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...
1C#double强制转换成int比如(int)(double d)这样转换是舍去小数取整,Convert.toint32(double d)是四舍五入取整,那我想要如果有小数直接进1取整,有没有这样的方法 2 C#double强制转换成int 比如(int)(double d)这样转换是舍去小数取整,Convert.toint32(double d)是四舍五入取整,那我想要如果有小数直接进1取...
两个数据相乘,获取到的值,是double类型,需要转为,int 类型。备注一下(MySQL) CONVERT((p.totalCount)*(r.rate)/100 ,SIGNED) as groupTotal,selectr.rate,c.groupName,CONVERT((p.totalCount)*(r.rate)/100,SIGNED)asgroupTotalfromxxx.notify_content_setting_newc
variableiwithMath.Ceiling()function in C#. The(int)is used to cast the double value returned by theMath.Ceiling()function to an integer value. The problem with this approach is that it always returns the next integer value. For example, the float value10.1is also converted to the integer ...
