why don't you just stick all your comments at the end.
you've written absolute rubbish.
To say that 2^3 is binary is as stupid as saying that
9^2 is not decimal (saying it's base 9).
And this thread was not talking about GHz, but Megabytes. And if you
measure Megabyte as 2^20 as is done, it doesn't mean the number is in
binary.
If you'd ever read of how computers store floating point numbers then
you'd know. It's along the lines of converting the mantissa and
exponent into binary. Because they are not in binary.
I'm sure you know this, but we seem to be having a communication
problem. It's your "style" that's the problem.
So go on, break the whole post up with comments after every single
line repeating the same denials and dismissive buzzwords that have
become your rotten trademark.
