Convert.ToInt32(float)方法用于将特定的浮点值(单精度浮点数)转换为其等效的整数(int 32字节带符号数字)。
语法:
int Convert.ToInt32(float value);
它接受浮点值/变量作为参数,并返回其等效的带符号整数。
示例
Input: decimal a = 1023.12f; Output: 1023 Input: decimal a = 1023.56f; Output: 1024
码:
using System; using System.Text; namespace Test { class Program { static void Main(string[] args) { float a = 1023.00f; float b = 1023.56f; float c = 1023.12f; Console.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType()); Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType()); Console.WriteLine("value of c: {0}, type of c: {1}", c, c.GetType()); //converting to Int32 & printing values & types Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType()); Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType()); Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(c), Convert.ToInt32(c).GetType()); //按ENTER退出 Console.ReadLine(); } } }
输出结果
value of a: 1023, type of a: System.Single value of b: 1023.56, type of b: System.Single value of c: 1023.12, type of c: System.Single value: 1023, type: System.Int32 value: 1024, type: System.Int32 value: 1023, type: System.Int32
