Money
If a dollar figure is rounded to the nearest dollar, it should be written without cents.
For example: She borrowed $20 from me.
If there is change, include cents. Where it makes sense, round to the nearest dollar.
For example: The cashier gave me back $20.35.
If the monetary value is not in Canadian dollars, indicate the denomination in front of the amount.
For example: The research grant is valued at US$2 million.
For example: The research grant is valued at 2 million euros.
