الميزات:
- Unit definition and manipulation,arithmetic operations with quantities,unit conversions (metric,imperial,custom),dimensional analysis,integration with NumPy for array operations,handling of uncertainties (optional,via `uncertainties` package),string parsing of units,pretty printing of quantities,extensive built-in unit definitions (SI,US,atomic,etc.)
التسعير:
- مجاناً
- Ensures dimensional consistency in calculations, helps prevent unit errors, highly flexible and extensible, good integration with NumPy, excellent documentation, actively maintained.
- Can add a slight performance overhead compared to raw numerical calculations (though often negligible), can be verbose if units need to be attached to every number explicitly, requires careful definition of custom units or contexts.
