1-10
All numbers or values to the left of the radix point are whole numbers, and all numbers to the right of
the radix point are fractional numbers.
Let’s look at the binary number 101.1 on a bar graph:
Working from the radix point to the right and left, you can determine the decimal equivalent:
Table 1-2 provides a comparison of decimal and binary numbers. Notice that each time the total
number of binary symbol positions increase, the binary number indicates the next higher power of 2. By
this example, you can also see that more symbol positions are needed in the binary system to represent the
equivalent value in the decimal system.
