C#Convert.ToInt32(float)方法-将float值转换为int
C＃Convert.ToInt32(float)方法
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（int32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
