bean-query rounding too much due to fractional_common

[Andrzej Kotulski]

I have a problem when running bean-query - it's rounding numbers too
much which leads to wrong results in csv file I generate from it.
Is there a way to force set `fractional_common` somewhere?
Ideas:
1. I use custom importer to produce transactions, maybe there is a way
to automatically add two fractional zeroes to the transaction?
2. Or maybe I can set it explicitly for that currency?
3. For now I did this: add two fractional zeroes to most transactions
manually, this will force fractional_common=2

Use case is that I'm tracking time in quarter increments (15 min = 0.25
hr) but most of my "transactions" are either full hours or half hours.
This leads to deriving `fractional_common=1` which leads to reporting 15
minutes as 0.2 hours.

I attach file I used to illustrate the problem

$ bean-query test.beancount 'SELECT date, number WHERE account ~
"Expenses:Bills" AND month(date) = 5'
   date    numb
---------- ----
2019-05-03 15.5
2019-05-10 15.5
2019-05-20  5.2
-- SHOULD BE:
-- 2019-05-20  5.25

$ bean-doctor display_context test.beancount
USD             : sign=1   integer_max=4 fractional_common=1  
fractional_max=2   "-0000.0" "-0000.00"
__default__     : sign=0   integer_max=1 fractional_common=_  
fractional_max=_   "0.*" "0.*"

Long story short, not right now.

I've been working on it though, a couple of new options to override this and set it explicitly, that is an obvious annoyance and you're not the first to come across it.

I just haven't been able to find the time to finish this properly.

It's "top of mind" though (if this buzzword makes sense).
