BitConverter.DoubleToInt64Bits() Method in C#


The BitConverter.DoubleToInt64Bits() method in C# is used to convert the specified double-precision floating-point number to a 64-bit signed integer.

Syntax

Following is the syntax −

public static long DoubleToInt64Bits (double val);

Above, Val is the number to convert.

Example

Let us now see an example to implement the BitConverter.DoubleToInt64Bits() method −

using System;
public class Demo {
   public static void Main(){
      double d = 5.646587687;
      Console.Write("Value = "+d);
      long res = BitConverter.DoubleToInt64Bits(d);
      Console.Write("\n64-bit signed integer = "+res);
   }
}

Output

This will produce the following output −

Value = 5.646587687
64-bit signed integer = 4618043510978159912

Example

Let us see another example −

using System;
public class Demo {
   public static void Main(){
      double d = 0.001;
      Console.Write("Value = "+d);
      long res = BitConverter.DoubleToInt64Bits(d);
      Console.Write("\n64-bit signed integer = "+res);
   }
}

Output

This will produce the following output −

Value = 0.001
64-bit signed integer = 4562254508917369340
