虽然看起来很愚蠢，从technical writing的角度来看，这是避免歧义的最好办法。
好像million和trillion在不同的欧洲语言里有不同的意思。

When using RMB, USD instead of the currency symbol ￥or $, we should put RMB or USD after the figures. Check out these websites: http://www.currencysource.com/tables/USD/100X_USD.htm

According to the EU Translation Style Guide, currency symbols should precede the figures, e.g. USD 1 million rather than 1 million USD.

The currency abbreviation precedes the amount and takes a space: FRF 2 400; EUR 3 500; EUR 2 billion When used, currency symbols are closed up: $100; £78; €120".

In country-specific articles such as Economy of Australia use only the symbol specific to the country, in this case $, with an italicized note placed at the top of the article to make this clear.

In articles which are not country specific, such as Wealth, use ''[[United States dollar|US$]]100'' or ''one hundred [[United States dollar]]s''. Use the most commonly used English abbreviation, and link to the relevant article only at the first usage. If there is no common English abbreviation or symbol, use the ISO 4217 standards.

In countries where the euro is used, do not place "EU" or similar prefix before the € sign.

When a currency abbreviation is placed in front of a number, those which end in a symbol (such as GB£ or €) should not be separated from the number. Those which end in an alphabetic character (such as RMB) should be separated by a single, non-breaking space ( ).
