A double entry system stores both values (and makes teh transaciton balance):
|
|
|
|
double entry states that value1+value2+value3+ ... = 0
|
|
where each value is recorded in a different account.
|
|
A value is value=exch-rate*amount (for currency accounts)
|
|
value=price*num-shares (for stocks/mutual-funds)
|
|
|
|
Thus, buying a widget in japan and using dollars to pay for it would appears
|
|
like so:
|
|
|
|
SpendAcct: (an oridnary bank/cash acct valued in USD)
|
|
----------
|
|
Date xfer from memo cost
|
|
1/5/99 [YenAcct] Buy widget $1.00
|
|
|
|
|
|
YenAcct: (a currency trading account valued in yen)
|
|
--------
|
|
Date xfer from memo purchase rate
|
|
1/5/99 [SpendAcct] Buy widget Y150 0.00667
|
|
|
|
|
|
The engine links together all three of these values (1.0, 150, 0.00667)
|
|
permanently and makes it imposssible to change one without changing another,
|
|
so that the grand total is always zero.
