About InaCalc.Net

Enable advanced calculations in your accounting or spreadsheet application.

InaCalc.Net supports conventional math operators and functions and is suitable for heavy-duty number crunching. It also supports other data types, such as string, date-time, logical, and operators and functions for these data types. It allows defining variables and sets of related formulas that implement spreadsheet-like recalculations.

The InaCalc component integrates expression parsing, evaluating, and dependent formula recalculation.

The InaCalc component is useful in two general areas; when: a formula has to be defined and evaluated at runtime.

For example: if the end user is allowed to enter a formula that will be evaluated and used. And: when a set of formulas that depend on each other are defined, configured, and evaluated at run-time.

The control contains the following main objects:

  • InaCalcManager Object
  • InaCalcAtoms Object
  • InaCalcAtom Object
  • InaFunctionSet Object
  • InaFunction Object
  • InaCustomFunction Object

Atoms are the main structure unit in InaCalc engine. Generally they correspond to spreadsheet cells. InaCalcAtom class manages each individual atom. The atoms are identified by their names. An atom can accept an arbitrary string value as name. Each atom contains a value.

Formulas are superposition of operators and built-in function on constant values and variables. They are comprised of the following elements:

  • Constants and Values
  • Variables
  • Operators
  • Functions
