Method

StringformatGuidToDashedNotation(String hexValue)
Returns dashed GUID notation formatted from simple hex-encoded binary. 
if (hexValue == null) {
    return null;
StringBuilder sb = new StringBuilder();
sb.append(hexValue.substring(6, 8));
sb.append(hexValue.substring(4, 6));
sb.append(hexValue.substring(2, 4));
sb.append(hexValue.substring(0, 2));
...
StringformatHEX(byte[] btValue, int iOffset, int iLength)
format HEX 
int iLastOffset = iOffset + iLength;
if (btValue.length < iLastOffset || iLength < 1)
    return "";
StringBuffer value = new StringBuffer();
for (int i = iOffset; i < iLastOffset; i++) {
    byte l, h;
    h = (byte) ((btValue[i] & 0xF0) >>> 4);
    if (h < 10)
...
StringformatHex(double theG)
format Hex 
int value = (int) (theG * 256);
String retVal = Integer.toHexString(value);
