This fix corrects a display issue in project budget management where an unused budget (zero spending) was incorrectly showing "-0%" instead of "0%". The fix ensures that when no budget has been spent, the system properly displays zero percent rather than a negative zero value, improving the accuracy of budget status reporting.

Steps:
- Install the project
- Enable Budget management from settings
- Create project
- Click on set status button inside your project
- Create budget

Issue:
- If budget is not used for expenditure then instead of showing 0% , it displays
 -0% which is incorrect.

Cause:
- float value of 'cost' i.e. 0.0 leads to generation of negative value

Fix:
- Issue is been fixed by applying condition if cost equals 0.0
