Template:To USD round/doc

This template converts a value given in the national currency of a given country to a round US dollar figure. The intended use is for large round figures, when you don't want €3.2 million turning into US$, you just want a round figure like US$. It tries to mimic the same number of significant figures, as are present in the original amount. The template uses values published by the IMF.

Parameters
There are three unnamed parameters, and one named parameter:


 * 1 is the amount in local currency to be converted to US dollars. Required.
 * 2 is the name or 3-letter ISO code of the country whose currency is being converted. Required.
 * 3 is the year to use for the US dollar exchange rate against the currency of the other country. Possible values: see below. Optional; default =.
 * sf is number of significant figures. The converted value is displayed to that precision. Optional; the default is the number of significant figures in the amount given in param 1.

Examples
