Method Detail

unsigned

public static int unsigned(byte b)

Get the unsigned value of a byte.

Parameters:

b - byte value

Returns:

unsigned value between 0x00 and 0xFF

unsigned

public static int unsigned(short s)

Get the unsigned value of a short int.

Parameters:

s - short value

Returns:

unsigned value between 0x0000 and 0xFFFF

unsigned

public static long unsigned(int i)

Get the unsigned value of an integer.

Parameters:

i - int value

Returns:

unsigned value between 0x00000000 and 0xFFFFFFFF

compareUnsigned

public static int compareUnsigned(byte b1,
                                  byte b2)

Compare two bytes as if they are unsigned.

Parameters:

b1 - first byte, interpreted as unsigned 8 bit value

b2 - second byte interpreted as unsigned 8 bit value

Returns:

less than 0 if unsigned(b1) < unsigned(b2), greater than 0 if unsigned(b1) > unsigned(b2), or 0 if unsigned(b1) == unsigned(b2)

compareUnsigned

public static int compareUnsigned(short s1,
                                  short s2)

Compare two short integers as if they are unsigned.

Parameters:

s1 - first short integer, interpreted as unsigned 16 bit value

s2 - second short integer interpreted as unsigned 16 bit value

Returns:

less than 0 if unsigned(s1) < unsigned(s2), greater than 0 if unsigned(s1) > unsigned(s2), or 0 if unsigned(s1) == unsigned(s2)
