1668 Ans. 2-29. Octal-to-Hexadecimal Conversion Like hexadecimal-to-octal there are two methods for converting octal-to-hexadecimal. The first method is to convert the given octal number to its binary equivalent and then from binary to hexadecimal. The second method is to convert octal-to-hexadecimal first and then from decimal-tohexadecimal. However the first method is much simpler and convenient. The procedure for conversion from octal-to-hexadecimal is as given below: Step 1. Write the octal number.

Example 2-31. Convert the number 15110 to its equivalent hexadecimal number. Solution. Given : The number = 15110 Created with Print2PDF. com/ 50 A TEXTBOOK OF DIGITAL ELECTRONICS We know that we can use the repeated division by 16 for converting a decimal number to its haxadecimal equivalent. Using division by hand, we get, Top 151 ÷ 16 = 9 with a remainder 7 LSD 9 ÷ 16 = 0 with a remainder 9 MSD Bottom Since the quotient is zero, so we will stop the further division. Reading the remainders from bottom to top, the hexadecimal number is 97.
