#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.General features of #Calculation:-Arithmetic, Logical, Bitwise and Relational operation-String operation-Date&Time operation-Matrix and Array operation-More than 110 Built-In Functions-Component constant and expression constant support-Alias for operators and functions-Unlimited nesting of expressions-Auto-detection of errors-"Simulate the exact value" operation-Two kinds of return values - string and numerical-Types of return values - Number, String, Datetime and Matrix-Upper case and lower case can be used interchangeably in expressions-Ansi chars and some unicode chars can be used in the expression-Scientific notation for numerical values-Custom-variable support-Comments can be used in the expression to evaluate-Custom functions can be created and used in expressions-Mixed operation among Binary, Octal, Decimal and HEXadecimal numbers-"Round Operation" according to desired precision-Base-N(2,8,10,16) results can be shown-Matrix and Array result support |
