Actually, after further thought this is not as accurate as you might
want. If you are looking to calculate 0.1 of your total increase
rounded to the nearest dollar that is different than summing the
rounding of all the individual increases. Ideally you would apply the
rounding on the reporting end, which is easy to do:
16:46:55 ~/FinanceData (master) > ledger bal 'Tithe Owed'
$ -1.75 Liabilities:Tithe Owed
16:47:11 ~/FinanceData (master) > ledger bal 'Tithe Owed' --format
"%10(floor(amount)) %20(account)\n"
$ -2.00 Liabilities:Tithe Owed
Which shows that I am slightly ahead on my tithe...
Of course it is much harder if you was a consolidated report of lots
of accounts, with only the Tithe Owed account rounded in this
fashion...it is possible, just harder...let me know if you want to see
a format string that could do that...
