Reading Assignment: Hexadecimal Number

1. What is the difference between hexadecimal and decimal numbers?
   Hexadecimal uses 16 digits (base 16), instead of 10 digits (base 10) in Decimal.

2. Which are the extra “digits” we get in hexadecimal?
   A, B, C, D, E, and F.
   A to F is counted as 10 to 15 in decimal mode.

3. What is the difference between using lower case or upper case letters?
   There are no difference. It mean the same.

4. What is hexadecimal for 34? (Use your head!)
   34₁₀ (decimal, base 10) = 22₁₆ (hexadecimal, base 16)

[Joeyj007]

1. What is the difference between hexadecimal and decimal numbers?
   Hexadecimal uses a set of 16 unique digits. Decimal numbers is a base 10 number system and is uses a collection of 10 unique digits.

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

3. What is the difference between using lower case or upper case letters?
   There is no difference.

4. What is hexadecimal for 34? (Use your head!)
   22 is hexadecimal for 34 decimal.

[YosephKS]

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

Hexadecimal is a base 16 numbering system and usually used within computer systems, while decimal numbers is base 10 numbering system, which is perfect and very intuitive for creatures with 10 fingers (e.g. humans).

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 are no distinction between using lower case or upper case letters.

4. What is hexadecimal for 34?

34 (decimal) = 3 * 10 ^ 1 + 4 * 10 ^ 0 = 2 * 16 ^ 1 + 2 * 16 ^ 0 = 22 (hexadecimal)

[Hirbed]

1 What is the difference between hexadecimal and decimal numbers?
Hex use base 16 and decimal use bas 10

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?
None difference at all

4 What is hexadecimal for 34? (Use your head!)
0x34(HEX) = 316 + 4=48+4=52 in decimal, but the question was what 34 decimal is in hex=lets try it out, 216=32 =hex(20) not yet 34 so add 2 to hex(20)=0x22

[B_S]

1. hexadecimal is just a way to keep counting beyond 10 (to 16) before you roll over your most significant digit; that makes for differences in that numbers are represented more compactly, easier to convert between them and binary, and looking much cooler when you can read/write them.
2. the extra digits are all those beyond 9 as letters, i.e. a, b, c, d, e, f
3. lower case v. upper case makes NO difference
4. 0x22 is how one might write decimal 34

[REGO350]

1. Decimal numbers top out at 9 before going to the next digit while hexadecimals top out at f (15 in decimal) before going to the next digit. Often times, hexadecimals are prefixed with 0x.

2. In hexadecimals the extra digits we get are a,b,c,d,e,f (10,11,12,13,14,15).

3. Hexadecimals are not case-sensitive.

4. Hexadecimal for 34 is 22.

[Kerux_api]

1. Hexadecimal numbers are base 16 bunbeda an Decimal numbers are base 10 numbers.

2. A B C D E F

3 No difference at all.

2. a,b,c,d,e,f
3. No difference.
4. 22

[h0h]

1. Decimal is base 10 which restarts after 10 and hexidecimal is base 16 which restarts after F.

2. A - F

3. There is no difference between using upper and lower case.

4. 0x22

What is the difference between hexadecimal and decimal numbers?

Decimal numbers have a base of 10, where you can count from 0-9 (10 digits), before adding an additional 1 before restarting counting.

Hexadecimal is very similar to this, however it is base 16, where the are the regular decimal digits of 0-9 (10 digits), PLUS another 6 digits as a continuation; A - F.

So when you count over 9 in hexadecimal, you count A as 10. And then B = 11, C = 12, D = 13, E = 14, F = 15.
And then you start back from 0, but suffix a 1 before counting again to create 16 (so 10 in hexadecimal would actually be 16 in decimal).

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

The extra digits are alphabetical to represent the additional 6 numbers above 9.
They are:
A, B, C, D, E, F

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

There is no functional difference between lower and upper case letters in Hex.
You can use them however you wish, in whatever combination of upper and lower case.

What is hexadecimal for 34? (Use your head!)

34 in Hexadecimal would be = 0x22

I hope I’m right!

[RBIG]

1. Hexadecimal numbers consists of a 16 base digits (0-9 + A-F) opposed to decimal that uses 10 digits (0-9)
2. The extra digits are the first six letters of the alphabet (A-F)
3. There are no differences as they are interchangable
4. 22

[MrSeven]

1. Hexadecimal numbers use 16 digits to represent a number, while decimal numbers use 10.
2. The extra digits in hexadecimal are ‘A to F’.
3. There is no difference between using lower case or upper case letters.
4. It’s 22.
