Like this:

C#

private Single ConvertHexToSingle (string hexVal) {
          try {
              int i=0, j=0;
              byte[] bArray = new byte[4];
              for (i = 0; i <= hexVal.Length-1; i += 2) {
                  bArray[j] = Byte.Parse (hexVal[i].ToString() + hexVal[i + 1].ToString(), System.Globalization.NumberStyles.HexNumber);
                  j += 1;
              }
              Array.Reverse (bArray);
              Single s =  BitConverter.ToSingle (bArray, 0);
              return (s);
          } catch (Exception ex) {
              throw new FormatException ("The supplied hex value is either empty or in an incorrect format.  Use the " +
                  "following format: 00000000", ex);
          }
      }

Good luck!
