TbcParser - Math Expression Parser component for Delphi 2.8

TbcParser is a VCL component that can be used with Borland Delphi, Kylix and Borland C++ Builder.

TbcParser evaluates mathematical expressions given as strings at runtime.

Features are:

*Easy to use, simple API.
*Comes with predefined functions.
*Users can create custom functions/variables.
*Optimization: Constant expression elimination for repeated tasks.
*Analytical Operators: +, -, /, *, ^, %
*Logical Operators: <, >, =, &, |, !, <>, >=, <= [less, greater, equal, and, or, not, etc]
*Paranthesis: (, {, [
*Functions in the form of: f(x,y,z,...)
*IF(condition,case1,case2) is supported
*List of predefined functions is available in the documentation.
*Delphi source code is included.

An example of a simple expression is : LN(X)+SIN(10/2-5)

When parsed, this expression will be represented as: since the SIN(10/2-5) is in fact SIN(0) which is a constant and is 0.

Thus, in a loop, if you change the value of X and ask for the value of the expression, it will be evaluated quite fast since SIN(10/2-5) is not dependent on X.

X and Y are predefined variables. You can create your own variables as needed.

There are many predefined mathematical functions. They are listed in documentation. You can create your own functions as needed.
