#23935: DecimalField in admin can show up as Scientific Notation
-------------------------------+--------------------------------
Reporter: xblitz | Owner: nobody

-------------------------------+--------------------------------
In the django admin, if a DecimalField's value is lower than 0.000001
displays as Scientific Notation (ex: 1E-7) since python Decimals converts
automatically to a scientific notation (exponential) ex:
Decimal("0.0000001") = Decimal('1E-7')
this is mostly visible when using Postgresql since DecimalFields with a
value of 0 are saved with the decimal precision higher than 6 , ex:
0.00000000 then in the admin instead of seeing 0 or 0.00000000 it is
displayed as 0E-8
the bug can be fixed by converting the Decimal to a fixed point value in
admin/utils.py:
