#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
