Nevron Open Vision (NOV) implements a complete and feature rich support for formulas, that aims to allow the development of different high-end modules for which strong formula support is essential.

Formulas are currently used in the DOM Formula Expressions, and as such provide the means for versatile many-to-one functional binding scenarios that are available to all products built upon the DOM.

The following list outlines the major features of the NOV Formulas module:

• Operators - complete set of arithmetic, comparison, logical and bitwise operators that let you author compact formulas.
• Functions - complete set of functions that let you perform versatile mathematical calculations as well as perform different text, array, type and flow processing tasks.
• Support for measures - complete support for measures (numbers with associated measurement unit) and for common arithmetic and mathematical operations with measures (measurement units algebra).
• Support for scopes and local variables - support for statements, scopes and local variables, that is indeed a rare feature in formula engines.
• Support for arrays - strong support for arrays and operations with arrays. Array operations are essential for spreadsheets and data analysis.
• Performance - the formula engine is specially optimized for performance.

All examples related to the NOV Formulas assume that you are using the Nevron.Nov.Formulas namespace and that you have referenced the Nevron.Nov.Presentation.XXX.dll for the specific runtime that you target.
