float IEEE 754 to hex

Use...

string Res=Convert.ToString(754,16);

the 2nd parameter (16) represents the base.

HTH

Smg.

PS. to convert back to decimal (from hex) - use...

int Res=int.Parse(InHex,NumberStyles.HexNumber)

Are you asking how to get the 4 hex bytes that make up the float?

If so, try BitConverter.GetBytes()

I'am trying to convert a floating point value (following the IEEE standard 754) 11.0 to this number: 1093664768.
I'am sorry but I'm not sure about the steps I need to do to get the second number.

I've got the solution. A friend of mine, have suggested it.

float a = 11.0F;
uint myUint = BitConverter.ToUInt32(BitConverter.GetBytes(a),0);
