Summary

0008134: Double representation should not be used for numbers as it is inprecise

Description

Double's are still used as intermediate representation in two places. Depending on values and configured precision this leads to wrong numbers displayed to the user.

XmlEngine/DataGrid (still) use Double when formatting according to formats defined in Format.xml

Steps To Reproduce

- Go to MRP -> Manufacturing plan
- Enter a header
- Enter a single line
- Execute the following sql in the underlying database (just to shortcut the process of entering this value):
update mrp_run_productionline set qty = '0.77777777777777777777777777';
- Last step changes the quantity of all Manufacturingplan lines to this value.
- edit config/Format.xml
change the formatOutput value for "qtyRelation" to "#,##0.###############################"
- display the manufacturing plan line again and so that not the correct value (as entered in the update step) is displayed but a different one.
- The correct value should be displayed as the configured Format.xml entry has more digits as the example quantity value.

Proposed Solution

Fix XmlEngine & DataGrid to not use double as intermediate format when formatting numbers.
