#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 run-time. #Calculation Component supports conventional math, string, date&time, logical operators and functions, and is suitable for heavy-duty number crunching. It also allows defining variables and sets of related formulas that implement spreadsheet-like recalculations. It can also support Matrix and Array operations (just like MATLAB), comments, different numerical systems and custom functions in expressions.
