> Given a currency field of CurrencyFieldType, the following asymmetric rates:
> {code:java}
> <rate from="SGD" to="USD" rate="0.72204658296750000000" />
> <rate from="USD" to="SGD" rate="1.45506540000000000000" /> {code}
> and a price field with a value of "24.500000,SGD"
> The following usage of the currency function as a pseudo-field in a query returns incorrect values:
> {code:java}
> curl -s 'http://10.43.41.81:32080/solr/product_details/select?fl=price,price_sgd%3Acurrency(price,SGD)&fq=id%3A57373P16&q=*%3A*&rows=1'
> {
>   "responseHeader":{
>     "zkConnected":true,
>     "status":0,
>     "QTime":0,
>     "params":{
>       "q":"*:*",
>       "fl":"price,price_sgd:currency(price,SGD)",
>       "fq":"id:57373P16",
>       "rows":"1"}},
>   "response":{"numFound":1,"start":0,"docs":[
>       {
>         "price":"24.500000,SGD",
>         "price_sgd":25.74}]
>   }} {code}
> I have traced this to the fact that CurrencyFieldType.getValueSource returns a value that is first converted to the default currency.  When dealing with asymmetric rates this always risks introducing conversion errors.
