**ARITHMETIC OPERATION AND CONVERSION DONE BY COMPUTER**

**As we have seen in previous post that arithmetic computation is an important thing in calculation, if a person doesn’t know arithmetic computations,he will be doomed to be in trouble during calculations that happensin everyday life.So it is necessary to learn arithmetic computation.So in this post I am going to take one step further.I am going to write about octal and hexadecimal numbers.**

Now let us discuss some arithmetic conversion.Let us see what is octal and hexadecimal numbers used by digital computer.

The conversion from and to binary, octal and hexadecimal plays an important part in digital computers.Since 23 = 8 and 24 = 16 each octal digit corresponds to three binary digits and each four binary digit corresponds to one hexadecimal digit.

The conversion of from binary to octal is easily accomplished by partitioning the binary into group of three digit each, starting from binary point and preceding to the left or to the right…
