# 62 in ASCII

Our teacher sent us a pdf and it says that 62 on base 10 is equal to 0011 0110 0011 0010 according to ASCII character set ( idk if he refers to that ASCII we know of or something else ) and in BCD it is 0110 0010, I got the BCD one but I couldn't figure out how that ascii one is encoded, is it correct, if so how does it work?

it could be because 62 is treated as a String because:
0011 0110 = ascii for 6
and
0011 0010 = ascii for 2
so combined they are 0011 0110 0011 0010 which is 62, 6 next to 2 not the int 62.

"62" ASCII in unpacked BCD is...
"62" ASCII in packed BCD is...
PS: In Romania, we have an expression about Turkish, confirming your "... one thing can mean a lot..."
In case of Romanian language, we have a lot of words, which can be different in each geographic region, but as a language, there are a lot of words. We have language influences from latin, slavic, turkish, germanic and maybe more.

Romeo Cojocaru as it seems the way he explained things on pdf leads to some misunderstandings like saying 62 on base 10 for both number and "62", a string, if he were to say like "62" in ascii is this and 62 on base 10 is that, then it'd be okay, especially in Turkish where one thing can mean a lot it's sometimes difficult to understand even for natives.

Are you sure that 62 is 0110 0010 on 8 bits (byte)?
MSB is sign bit, so you have values from -128 to 127. If MSB is not sign bit, you have values fro 0 to 255...
Anyway, 0110 0010 is not 62. But,
0011 1110 is 62.
While that binary number on 16 bits is definitely not 62, but maybe your teacher knows things that I don't know. đ

Romeo Cojocaru that 0110 0010 is encoded using BCD meaning every 4 bit represents every digit of the number so you calculate these 4 bits seperately and its correct but the problem is with the ascii one

InÂ byte-oriented systems (i.e. most modern computers), the termÂ unpackedÂ BCD[1]Â usually implies a full byte for each digit (often including a sign), whereasÂ packedÂ BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9. The precise 4-bit encoding, however, may vary for technical reasons (e.g.Â Excess-3).

So, it's like Bahhađ§ said. In ASCII table you see the decimal value for each char: 50 for "2" and 54 for "6". Then, convert in binary 54 and 50 on 8 bits (as unpacked BCD).
