Tja, manche Börsen runden. Mal mehr oder weniger.
Hier die Rundungs-Regeln für CEX.IO:
ROUNDING POLICY
For all financial calculations, CEX.IO uses a rounding policy which rounds to the 8th digit after the separator, in the favour of the platform.
Example:
If you wish to buy 0.1 GHS per 0.0595678678 BTC
The amount of BTC you will be spending is 0.1 * 0.0595678678 = 0.0059567868 BTC
1) The system will take 0.0059567868 and multiply it by 108, making it 595678.68
2) Afterwards the system will pick the minimum integer larger than 595678.68, which is 595679
3) Hence, to buy 0.1 GHS - you will be spending 0.00595679 BTC
If you decide to sell 0.1 GHS per 0.0595678678 BTC
The amount of BTC you will be getting is 0.1 * 0.0595678678 = 0.0059567868 BTC
1) The system will take 0.0059567868 and multiply it by 108, making it 595678.68
2) Afterwards the system will pick the maximum integer smaller than 595678.68, which is 595678
3) Hence, to sell 0.1 GHS - you will be earning 0.00595678 BTC
Es gibt aber auch Börsen die "nur" mit 5 Stellen nach dem Komma arbeiten, der Rest "fällt" hinten rüber.
