in reply to Re^3: When I see "10", I think:in thread When I see "10", I think:
Using octal for 16-bit values is that it isolates bit 15 nicely.
FFFF(hex) = 177777(oct)
8000(hex) = 100000(oct)
7FFF(hex) = 077777(oct)
0000(hex) = 000000(oct)
If the left-most hex digit is 8 or higher, the high bit is set.
Which doesn't help you read the next 15 bits.
That's all you got?
You dig up an old thread to say: "Using octal for 16-bit values is that it isolates bit 15 nicely."
And when you are shown that isolating the high bit in hex is trivial; you then say; "Oh, but it's not about the high bit; its about the other 15".
Were you bored and just came looking for a argument?
Well here it is. Translating hex nibbles to binary is child's play. Every programmer worthy of the name does in their head without thinking.
The advantage over octal is obvious. (hint:byte alignment).
