示例1: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
Single value = .2f;
Single result1 = value * 10f;
Single result2 = 0f;
for (int ctr = 1; ctr <= 10; ctr++)
result2 += value;
Console.WriteLine(".2 * 10: {0:R}", result1);
Console.WriteLine(".2 Added 10 times: {0:R}", result2);
}
}
开发者ID:.NET开发者,项目名称:System,代码行数:17,代码来源:Single 输出:
.2 * 10: 2
.2 Added 10 times: 2.00000024
示例2: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
Single value = 123.456f;
Single additional = Single.Epsilon * 1e15f;
Console.WriteLine($"{value} + {additional} = {value + additional}");
}
}
开发者ID:.NET开发者,项目名称:System,代码行数:12,代码来源:Single 输出:
123.456 + 1.401298E-30 = 123.456
示例3: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
Single[] values = { 10.01f, 2.88f, 2.88f, 2.88f, 9.0f };
Single result = 27.65f;
Single total = 0f;
foreach (var value in values)
total += value;
if (total.Equals(result))
Console.WriteLine("The sum of the values equals the total.");
else
Console.WriteLine("The sum of the values ({0}) does not equal the total ({1}).",
total, result);
}
}
开发者ID:.NET开发者,项目名称:System,代码行数:20,代码来源:Single 输出:
The sum of the values (27.65) does not equal the total (27.65).
If the index items in the Console.WriteLine statement are changed to {0:R},
the example displays the following output:
The sum of the values (27.6500015) does not equal the total (27.65).
