• ecMathExpr is an ActiveX (ocx) control for Visual Basic programs, for compiling and evaluating math expressions from within your VB projects.
• Expressions are compiled so they run 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 use the user-defined variables and 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)
