In the prev example 18. they have taken pound as base currency.
which one is the right one..作者: kingstongal 时间: 2011-7-11 19:53
I don't think it is unitless
The % change would differ if the base currency is different.
If you see EOC 4- the % change of baht in terms of dollar is -16.7 & % change in dollar wrt baht is 20 %
