Units & Dates
Mathematica Version 11 adds improvements to time series processing throughout the framework. Direct arithmetic and function applications just work; applying a function over windows now allows natural specifications such as monthly duration, as well as precise control over where the resulting value is placed in time. Generally, date and quantity support is more complete and natural. Time series are now produced and accepted by many functions in the system.
Mathematica Version 11 supports quantities across the probability and statistics functionality, fully automating conversion, propagation, and transformations - from data to models to correct interpretation.
Mathematica Version 11 expands on the extensive collection of different units and date functions, creating an expressive and intuitive system for working with physical quantities and dates. Enhancements include efficient array storage of quantities, new date forms and formats, and new date visualization functions to examine temporal relations.
