Wrong amount in small orders

[pc]

When i submit a bid wanting to buy 8 BTS @ 0.000132555 USD i get this in the orderbook.

Code: [Select]

0.0010 USD                7.54403 BTS                     0.000132555000 USD
Why i don't get the full 8 BTS?

For 8 BTS you'd have to pay .001060440000 USD. But USD is limited to 4 decimals, so you can either have 7.54403 for .001 USD or 8.29844 BTS for .0011 USD. Apparently the client is always rounding down.
