Question

does anyone know how to convert hexadecimals

Answer 1

I am completely and utterly lost. #22ad7f needs to be converted in base 16

Answer 2

isnt hexadecimal already in base 16?

Answer 3

Um seems more of a computer science question :/

Answer 4

Ikr

Answer 5

Unless you mean base 64

Answer 6

yeah its computer base
but its says i need to times by 16

Answer 9

me too

Answer 10

Answer 11

hexadecimal is base 16, so the numbers in each place go
0 1 2 3 4 5 6 7 8 9 A B C D E F

the place values are 1 16 256 4096 65536 etc.

#22ad7f is a hexadecimal number — both the presence of a,d,f and the leading # tell you that. I take it the problem is to convert it to the base 10 representation?

Answer 12

hexadecimal is base 16 ... digits go from 0 to F
based on 4 bits ....place values
0001 = 1
0010 = 2
0100 = 4
1000 = 8

1111 --> 15 or F
1010 --> 10 or A

Answer 13

Your place values are:

2*16^5 = 2*1048576
2*16^4 = 2*65536
a*16^3= 10*4096
d*16^2 = 13*256
7*16^1 = 7*16
f*16^0 = 15*1

add them up and you've got your value, base 10.

Answer 14

Ugh, I used to know all this stuff and binary calculating too, but alas I have forgotten it :(

Answer 15

oh thank you so much! that helped a lot.

Answer 16

@dumbcow gave an excellent explanation of the binary underpinnings. another variation is "octal" or base 8, which is not used so frequently now. There the bits come in groups of 3, values 0-7.

Answer 17

No mention of alternative bases can go without mentioning Tom Lehrer's infamous treatment: http://www.youtube.com/watch?v=Vetg7vWitTU

Answer 18

thank you so much guys

Answer 19

Whoops, that's the short version, it doesn't do both bases! This is the complete version: http://www.youtube.com/watch?v=DfCJgC2zezw

Answer 20

^THAT IS HALARIOUS lol

Answer 21

nevermind. i was thinking of something else

Answer 22

Yes, base^0 = 1 (base cannot equal 0).

@JA1 if you liked that, also check out his "Elements" song. Heck, check out all of his stuff :-)

Answer 24

xD already did it is too funny lol

Answer 25

the 10-year-old on staff here enjoys "Pollution", "Smut", I like "She's My Girl" and "Lobachevsky" is a great math-oriented one, too (Lehrer was a math professor for many years)

Answer 26

He is awsome, that's the content youtube needs lol
