C# | BitConverter。双 to t64 位()方法
原文:https://www . geesforgeks . org/c-sharp-bit converter-double toint 64 bits-method/
BitConverter。Double to t64 bits(Double)方法用于将指定的双精度浮点数转换为 64 位有符号整数。
语法:
public static long DoubleToInt64Bits (double value);
这里值是要转换的数字。
返回值:该方法返回一个 64 位有符号整数，其值相当于值。
以下程序说明了位转换器的使用。双 to t64 位(双)方法:
例 1:
// C# program to demonstrate
// BitConverter.DoubleToInt64Bits()
// Method
using System;
public class GFG {
// Main Method
public static void Main()
{
// declaring and initializing double value
double value = 1.2345678901234565;
// Display the double value
Console.Write("double-precision floating point: ");
Console.WriteLine("{0}", value);
Console.WriteLine();
// Converting double to long value
// using BitConverter.DoubleToInt64Bits()
// Method
long value1 = BitConverter.DoubleToInt64Bits(value);
// Display the 64-bit signed integer.
Console.Write("64-bit signed integer: ");
Console.WriteLine("{0}", value1);
}
}
Output:
double-precision floating point: 1.23456789012346
64-bit signed integer: 4608238818662570490
例 2:
// C# program to demonstrate
// BitConverter.DoubleToInt64Bits()
// Method
using System;
class GFG {
// Main Method
public static void Main()
{
// declaring and initializing double value
double value = 1.0;
// Display the double value
Console.Write("double-precision floating point: ");
Console.WriteLine("{0}", value);
Console.WriteLine();
// Converting double to long value
// using BitConverter.DoubleToInt64Bits()
// Method
long value1 = BitConverter.DoubleToInt64Bits(value);
// Display the 64-bit signed integer.
Console.Write("64-bit signed integer: ");
Console.WriteLine("{0}", value1);
Console.WriteLine();
// Display the Hexadecimal value
Console.Write("Hexadecimal value: ");
Console.WriteLine(value1.ToString("X"));
}
}
Output:
double-precision floating point: 1
64-bit signed integer: 4607182418800017408
Hexadecimal value: 3FF0000000000000
