This function:
GOOGLEFINANCE(("CURRENCY:EURAUD"))
works well in Google Sheets, I have searched the web up and down for some documentation regarding this function and how it is used, the closest I've got was this
http://www.google.com/finance?q=EURAUD
Does anyone know how to use this one? or where to find documentation regarding this function?
Here you go:

This is all the documentation that Google provides.
