Writing float values to hex

Klaz0r · Post by **Klaz0r** » Tue Jan 17, 2006 7:00 pm

Ok, I've seen the binary representation of a floating point number, and let me just say it's not pretty. Is there a simpler way to convert a floating point number into its hexadecimal equivalent without having to find out mantissas and 2s compliments and stuff? It would really help if I could get this in VB code.

If your using .Net:

Code: Select all

public static void GetBytesSingle( float argument )
{
	const string formatter = "{0,16:E7}{1,20}";

	byte[] byteArray = BitConverter.GetBytes( argument );
	Console.WriteLine( formatter, argument, BitConverter.ToString(byteArray) );
}

GetBytesSingle( 1.0F ); // outputs "00-00-80-3F"
GetBytesSingle( 15.0F ); // outputs "00-00-70-41"

If your using C\C++ you can just type cast it to a long and use itoa to get the hex value in a string

If you using VB6. I recommend you upgrade to VB.NET or even better, C#.NET
