hi,
ur sure about this ??...as i was trying to figure out why isnt it really
coming to the required number 1024000..as the difference is also big enough
to be rounded off....
if you can confirm it would be great....
as a matter of fact i i get 77 something in the lab it wouldnt be rounded
off to 80 to make me pass... :-) just kidding...
thanks for your immediate reply...
