- [ENH] Add abs() function to tracker calculations
Implemented the abs() function for tracker field calculations in Tiki. This change allows users to compute the absolute value of numeric fields in their tracker calculations.
Changes include:
- Added
Abs.php
tolib/core/Formula/Function
to define the new abs() function. - Updated
Currency.php
to integrate the abs() function where necessary. - Modified
Applicator.php
to support the parsing and execution of the abs() function in formulas.
These changes enhance the flexibility and functionality of tracker field calculations by enabling absolute value computations.
