- Add FLOOR function for rounding down to nearest integer
- Add ABS function for absolute values with type preservation
- Support all numeric types (int32, int64, float32, double)
- Comprehensive test suite with 20+ test cases covering:
  - Positive/negative numbers
  - Integer/float type preservation
  - Precision handling for ROUND
  - Null value error handling
