About Quantity Operations
UCUM quantity operations require dimensional compatibility between operands. The system automatically handles unit conversions when possible.
Arithmetic Operations
- Addition: Both quantities must have same dimensions
- Subtraction: Both quantities must have same dimensions
- Result uses the unit of the first operand
Comparison
- Returns -1 (less), 0 (equal), or 1 (greater)
- Automatically converts units for comparison
- Requires dimensional compatibility
