Review #Calculation component is a powerful calculation engine for your applications. This ActiveX component integrates expression parsing and evaluation. Generally speaking, #Calculation is very useful in two main areas: first, when a formula has to be defined and evaluated at runtime (for example, when the end user is allowed to enter a formula that will be evaluated and used); second, when a set of formulas that depend on each other are defined, configured, and evaluated at runtime. #Calculation Component supports conventional math, string, date&time, logical operators and functions, and is suitable for heavyduty number crunching. It also allows defining variables and sets of related formulas that implement spreadsheetlike recalculations. It can also support Matrix and Array operations (just like MATLAB), comments, different numerical systems and custom functions in expressions.
