将指定双精度浮点数转换为 C# 中的 64 位有符号整数
要把指定双精度浮点数转换为 64 位有符号整数,代码如下 -
实例
using System; public class Demo { public static void Main() { double d = 5.646587687; Console.Write("Value = "+d); long res = BitConverter.DoubleToInt64Bits(d); Console.Write("
64-bit signed integer = "+res); } }
输出
将输出以下内容 -
Value = 5.646587687 64-bit signed integer = 4618043510978159912
实例
让我们看另一个示例 -
using System; public class Demo { public static void Main() { double d = 0.001; Console.Write("Value = "+d); long res = BitConverter.DoubleToInt64Bits(d); Console.Write("
64-bit signed integer = "+res); } }
输出
将输出以下内容 -
Value = 0.001 64-bit signed integer = 4562254508917369340
