Ether price value and decimal-places of Token about itt HOT 4 OPEN

then, MAXNUM value constraint ("use only 128 bits of uint to prevent mul overflows.")
should be reconsidered for integer multiplication and division error.

The base unit is uint 1 and the decimalPlaces is only utilised by the client. It's up to the client to handle the fractional maths. No divisions are used in the contract at all to avoid rounding errors.

But I think safe division can be performed by restricting token amount and ether price parameter.
(restricting that ether price and token aboumt value should have trailing decimal (decimalplaces/2) zeros
for example, If decimal-places is 18, token amount value and ether price value should have 9 trailing decimal zeros..

And I hope decimal places of Token might be fixed to constant(=18) same as Ether.

There's simply no need to use fixed-point maths when you have no divides.
