rounding for amounts ?

[bvandenbon]

to round the prices I use the pricePrecision which is provided by the market() function.
is there a similar precision for the amounts. e.g. ETH should be 2 decimals I think, while XRP seems to be 0 decimals I think.

For amounts, there isn't a precision, but rather an amount of decimals. These can be acquired from the 'assets' call.
Make sure you understand precision and decimals are NOT the same. Take the number 3543.3526246, formatted with 5 decimals this becomes 3543.35262. Formatted with precision 5, it becomes 3543.4.
