, 4. 5 Note the notation for 16 notation, denoted by the letter H suffix, for example, BH means 16 binary number 11, or it can be represented by a 0X prefix, For example, 0x23 is 16 binary 23. Visual Representation 5 shows. 6 It is important to note that when you take four bits to the left (or right), the highest bit (lowest bit) is not able to fill four bits, You can make 0 on the leftmost (or rightmost) of the decimal point, and the conversion is shown in 6. 7 Take a look
