HEXADECIMAL (HEX) NUMBER SYSTEM The hex number system is a more complex system in use with computers. The name is derived from the fact the system uses 16 symbols. It is beneficial in computer programming because of its relationship to the binary system. Since 16 in the decimal system is the fourth power of 2 (or 24); one hex digit has a value equal to four binary digits. Table 1-5 shows the relationship between the two systems.
