Most of our arithmetic operations are performed with decimal numbers . The computer , however, does not use the decimal numbering system . It uses the binary numbering system, which is based on the number 2. This base 2 system uses only the digits and 1 to represent numerical values, and thus when completing computations involving decimals , the computer must essentially perform three steps :
1. It converts numeric data input from its decimal format into its binary equivalent .
2. It performs the desired arithmetic manipulations in binary .
3. It convert the binary results into their decimal equivalents for output .
Why does the computer do this ? The reason is simple. It is easier and faster for the computer than for people to accomplish the required conversion . Furthermore, the accuracy of the results is more certain .
