[FIX] Selfconsumption distribution coefficient decimal positions
Task: https://somcomunitats.openproject.com/projects/canal-2/work_packages/208/activity
In selfconsumption projects, the distribution coefficient (beta) must have 6 digits after the coma, not 5.
Why (7, 6)
and not (1, 6)
?
Because from what I understand the first number (total) represents what in Postgres is called precision
: "the total count of significant digits in the whole number, that is, the number of digits to both sides of the decimal point".
Odoo uses the (total, decimal)
information only to read the data from the DB, the columns in the DB is created as numeric
but without any info related to precision
or scale
. From what I understand Odoo just ignore the total
and just use decimal
for the rounding while reading.
EDIT:
While testing, I discovered that the rounding actually happens on the write. If you input 0,1234567
it will store 0,123457
. In any case... total
still not used.
