Interesting...I just had a look at this link, as well as its 
HTML-formatted counterpart at

http://www.imf.org/external/np/tre/sdr/db/rms_five.cfm

The first dataset (SDRs per Currency Unit) is reported to nine decimal 
places, while the reciprocal dataset is reported to six.

So:  should such a class round in accordance with the IMF policy, or 
would it be acceptable to store the first dataset and invert it as 
necessary, giving slightly different results?  In other words, which 
would give the "expected" performance to potential clients of the class?
