Character Coding

[Zero]

All this ASCII stuff and EBCDIC stuff is killing me.

Whats the difference between binary and binary coded decimal??

Binary is:

128 64 32 16 8 4 2

This is right yes? All the relavant numbers go under each section?

So whats BCD then?

And no pasting links from wikipedia and google cos I tried that already and theres no good explainations from there!

BCD is binary coded decimal but then again wat exactly are u looking for?

if u asking the difference between Binary and BCD ??


The difference between binary and BCD storage is that binary stores the entire value as a single binary number, whereas BCD encodes each digit independently. The results are not the same. For example, here's the value 1234 stored in binary and BCD format, using 2 bytes: Decimal: 1234
Binary: 00000100 11010010
BCD: 00010010 00110100

makes sense?

Ok elaborate on that last bit dude.

lets say a smaller number:

"26"

In binary it would be:

00011010.... correct?

So wat you saying is, in BCD "26" would be:

???

yes in binary it would be that,

and in BCD

BCD 26: 00100110

basically all u r doing is first writing binary for 2 and then binary for 6, thats how u get BCD value.

whereas in Binary u convert the whole number not break it up....

Ohhhhh OK....yep got it, thanks bro.

Oh and that database thingy we were on about few days back? I got 92% correct!

oh koolio... lol i bet the stuff u were asking me u got that wrong lol... but still that aint bad...
