| Description for Calculation Control |
| #Calculation Control - The Powerful Calculation Engine #Calculation is an ActiveX control designed for VB6/VB.net/VC++/VJ++/VC#.net. It is a powerful calculation engine for your applications. This ActiveX control integrates expression parsing and evaluating. Generally speaking, #Calculation control is useful in two general areas: first, 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); second, when a set of formulas that depend on each other are defined, configured, and evaluated at run-time. #Calculation control supports conventional math 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. Even it can support note-line and custom-functions in your expression. The powerful calculation ability, various functions, and the different modes of work give power and flexibility. Enable advanced calculations in your accounting or spreadsheet applications. All these are very EASY! Here is just a short list of control's major features: 1)Arithmetic operation 2)Logic and Bitwise operation 3)Relation operation 4)Built-In Functions 5)Constant support ,such as PI,E,TRUE, FALSE etc. 6)Alias for operators and functions ,eg."sh" and "hsin" is the same function 7)Unlimited nesting for expression 8)Auto detect errors 9)Table/Array operation supprot 10)"Simulate the exact value" operation 11)Two kinds of return value - string and numerical value 12)Upper case and lower case can be mixedly used in the expression 13)Ansi chars and some unicode chars can be used in the expression 14)Scientific notation for numerical value 15)Custom variable support 16)Note-line can be used in the expression you want to evaluate 17)Custom function can be created by the control and be used in the expression |
