More Hex Practice
(Not as done at Mugworts)

If there are not enough bits at the left to form a complete group of four, add zero bits to the left, (but be sure that it is clear by context how many bits you are describing). For example:

1010000010000010     =  
1010 0000 1000 0010  =  A082

Another example:

10100110101111      =  
10 1001 1010 1111   =
0010 1001 1010 1111 = 29AF

Usually '0x' is placed at the front of a pattern name to show that it is a hexadecimal pattern name:

0x0010  =  0000 0000 0001 0000
0xFACE  =  1111 1010 1100 1110

Please understand that hexadecimal pattern names are used by humans for talking about bit patterns. Inside the computer there are only bits and their patterns. Hexadecimal is used in books and documents (outside the computer) to describe these bit patterns.
