An equivalent unsigned value for 8 bits

toSigned

public static final long toSigned(byte value)

This method will convert the byte to an signed value

Parameters:

value - The most significant bytes

Returns:

An equivalent signed value for 8 bits

toUnsigned

public static final long toUnsigned(byte left,
                                    byte right)

This method will convert the two byte to an unsigned value

Parameters:

left - The most significant bytes

right - The least significant bytes

Returns:

An equivalent unsigned value for 16 bits

toSigned

public static final long toSigned(byte left,
                                  byte right)

This method will convert the two byte to an unsigned value

Parameters:

left - The most significant bytes

right - The least significant bytes

Returns:

An equivalent unsigned value for 16 bits

toSigned

public static final long toSigned(byte one,
                                  byte two,
                                  byte three,
                                  byte four)

This method will convert the two byte to an unsigned value

Returns:

An equivalent unsigned value for 16 bits

toUnsignedByteBytes
