How should exchange rates be formatted?
Ah, one of my bugbears, especially when the A$ and US$ are close to parity. You often see the ambiguous A$/US$ = 0.95. To remove the ambiguity, always make it clear which currency is the unit reference, place the currency symbol after the number, and show the conversion to three (or more if justified) decimal places, as in 1.00 $A = 0.952 US$. If the conversion rate is less than 0.01, multiply the reference currency by 100, 1000 or as required to give a rate above 0.01, as in 100 INR = 1.196 EUR.
