IEEC 十六进制32位浮点数与小数的相互转换

Question

请教如何将32位十六进制浮点数与十进制小数相互转换的函数。例如，如何将“41C8CCCD"转换成25.10；又如何将25.10转换成"41C8CCCD"

Answer 1

不好意思，我忘记说明需要在vb.net中使用，谢谢！

Answer 2

//C#

int num = 0x41c8cccd;
float num2 = *((float*) &num);
int num3 = *((int*) &num2);
Debug.WriteLine(num2.ToString());
Debug.WriteLine(num3.ToString("X"));

//VB.NET

 Dim num As Integer = &H41C8CCCD
 Dim num2 As Single = DirectCast(AddressOf num, Single*)
 Dim num3 As Integer = DirectCast(AddressOf num2, Integer*)
 Debug.WriteLine(num2.ToString)
 Debug.WriteLine(num3.ToString("X"))

我您回复的VB.NET代码贴到我的程序中测试，AddressOf 后面的num显示错误，提示是“后面的参数必须是某个方法的名称”；后面的*号也同样显示为错误，请教如何解决？万分感谢您的帮助。
