Reading Assignment: Hexadecimal Numbers

  1. What is the difference between hexadecimal and decimal numbers?
    Decimal is base 10 ranging from 0 to 9 per position. Hexadecimal is base 16 ranging from 0 to F (15)
  2. Which are the extra “digits” we get in hexadecimal?
    ABCDEF
  3. What is the difference between using lower case or upper case letters?
    There’s no difference
  4. What is hexadecimal for 34? (Use your head!)
    0x22
  1. The decimal number system has 10 digits the hexadecimal or base 16 has 16
  2. The extra digits in the hexadecimal are the letters A - F which represent the numbers 10 - 15.
  3. There is no difference between using the upper and lower case they represent the same value af is the same as AF

  • What is the difference between hexadecimal and decimal numbers?

*The biggest difference between hexadecimal and decimal numbers is the ‘base number’. Decimal is base 10 (from 0, it takes 10 digits to add a 1 to the start ‘10’) and Hexadecimal is base 16(from 0, it takes 16 digits to add a 1 to the start ‘10’. *

  • Which are the extra “digits” we get in hexadecimal?

After ‘9’ hexadecimal numbers use the letters ‘a’, ‘b’, ‘c’, ‘d’, ‘e’ and ‘f’.

  • What is the difference between using lower case or upper case letters?

There is no difference with the number when it comes to case sensitivity.

  • What is hexadecimal for 34?

1. What is the difference between hexadecimal and decimal numbers? Each one represents a different number systems base. Decimal has a Base-10 number system and Hexidecimal - a Base-16 number system.

2. Which are the extra “digits” we get in hexadecimal? A,B,C,D,E,F

3. What is the difference between using lower case or upper case letters? There is no representative difference. Upper and lower cases can be used interchangeably.

  1. Decimal numbers are in the base 10 numbering system whereby there a 10 digits (using the characters 0 through 9 ) that can be used in each column of a multidigit number (e.g. the number fifteen in decimal is written as ‘15’). Whilst Hexadecimal numbers are in base 16, whereby there are 16 digits (using characters 0 through 9, plus A through F for values of 10 through 15) that can be used in each column of a multi-digit number (e.g. the number fifteen in hexadecimal is written as ‘F’).

  2. The extra “digits” used in hexadecimal are ‘A’ (to represent 10), ‘B’ (to represent 11), ‘C’ (to represent 12), ‘D’ (to represent 13), ‘E’ (to represent 14), and ‘F’ (to represent 15).

  3. In Hexadecimal there is no difference between writting these extra digitals in upper or lowercase. Therefore A2CF == a2cf == A2cf == a2CF == a2Cf etc.

  4. To calculate the hexadecimal number from a decimal number by hand then long division and reminders can be used. Specifically divide 16 into the decimal number, recording the remainder (which becomes the left most significant digit in hexadecimal). Repeat this process, dividing the resulting quotient (of previous division) by 16 and again recording the remainder (which becomes the next most significant digit of the hexadecimal equivalent number). Repeat this process until the quotient is zero and the final remainder has been recorded.
    Therefore 34 / 16 = 2 (the quotient) with a remainder of 2. First (most significant) digit in hex is therefore ‘2’. Next 2/ 16 = 0 (the quotient) with a remainder of 2. The second (next most significant) digit in hex is also ‘2’.
    So 34 in decimal = 22 in hex (which can be written as ‘0x22’ to make it clear that its a hexadecimal number)

  1. What is the difference between hexadecimal and decimal numbers?

Decimal numbers use 10 unique digits, hexadecimal use 16 unique digits, so on top of the 10 existing from the decimal system, they incorporate 6 additional signs.

  1. Which are the extra “digits” we get in hexadecimal?

They are the first 6 letters of the alphabet, in uppercase: A, B, C, D, E, F.

  1. What is the difference between using lower case or upper case letters?

They both work, upper and lowercase would make a different in a numerical system where upper and lowercase letters would be 2 different signs, which is not the case in hex.

  1. What is hexadecimal for 34?

31 in hex is 1F, so 32 is 20, adding 2 to it: 22

I hope it is not hindering me to get a certificate handed out while not having completed assignments here in the chat forum but written by hand ? They can be scanned if needed thought

  1. decimal numbers have a basis10 while hexadecimal a basis of 16 (numbers 1-9 and letters A-F)
  2. letters A-F
  3. there is no difference at all

  1. Hexadecimal numbers are base 16, and decimal numbers are base 10.

  2. Hexadecimal numbers add the “digits” A, B, C, D, E, and F

  3. Hexadecimal numbers do not discriminate between upper and lower case letters, therefore 3aC is observed the same as 3AC

  4. 34 represented in hex would be 22

  1. Hexadecimal numbers are base 16 while decimal numbers are base 10.
  2. Hexadecimal get the extra digits a, b, c, d, e, f which represent decimal numbers 10, 11, 12, 13, 14, 15.
  3. There is no difference between lower and upper case in hex.
  4. 34%%16=2 (quotient 2 and remainder 2), and 2%%16=2. Therefore
    decimal 34=hexadecimal 22, which we can represent as 0x22 to indicate hex.
