I need several calculated fields added to my Odoo instance that can handle complex, multi-step mathematical formulas. All source values will be typed in directly by the user on the form view; as soon as a value changes the result should refresh automatically, respecting the usual Odoo onchange / compute conventions. The exact formulas include chained operations (parentheses, exponents, conditional branches) rather than simple addition or multiplication, so the code must stay readable and maintainable for future edits. I will provide the formulas in spreadsheet form once we start. Please deliver: • A small custom module defining the computed fields on the specified model(s). • XML that inserts the fields into the existing form view in a tidy layout. • A short README explaining where to tweak the formulas and any dependencies. Acceptance criteria: calculation accuracy matches my spreadsheets for at least ten test cases I will supply, no server errors in logs, and no performance lag when editing the form.
