Inaccurate fee calculations on Cryptsy

[thewarlok666]

It would appear that there is a problem calculating fees and totals. Also, besides dropping trailing zeros, Only 6 digit decimals being displayed. could this lead to inadvertent rounding (GREEN)?

Yes, there are 2 problems here:

• trading fee for the ltc/btc pair is not what Cyptsy said on their support page (they advertise 0.2 % for buy, 0.3% for sell)§. The ltc/btc pair is 0.25%/0.25%.
• only 6 decimals are displayed (instead of 8). When 8 decimals are displayed, the 2nd scenario works normally

Cryptsy provides an API method for calculating fees for a trade, but no method to retrieve the actual fee parcentage... so it means we have to call they API for every calculation (or make one calculation and work out the fee from there)

Edit: the API for calculating fees does not take a currency pair as input parameter, so it always returns 0.2%/0.3% for buy/sell orders. Only a few pairs seem to have a 0.25% fee; USD pairs, LTC/BTC, FTC/BTC, and I'm not sure which other ones...
