ecMathExpr is an ActiveX control for Visual Basic programs, for compiling and evaluating math expressions created at runtime, from within your VB projects...
* Compiled, runs faster than simple parser methods
* Define any number of variables and assign values to them.
* Pre-compile 'user-defined' functions to use in other math expressions.
* Compile multiple math expressions that can use the pre-defined variables and user functions.
* Evaluate (fast and repeatedly) any of the compiled expressions.
* Arithmetic operators: ( ) + - * / ^ \ mod
* Boolean operators: not, and, or, xor
* Logical operators: = > < <> >= <=
* Trigonometric functions: sin, cos, tan asin, acos, atan
* Hyperbolic trig functions: sinh, cosh, tanh asinh, acosh, atanh
* Internal functions: int, fix, sgn, sqr, fact, nCr, nPr, min, max, rnd
* Logarithmic and exponential functions: log, exp
* Logical if..then..else functions: iif(condition, if_true, if_false) |
