RunFormula: math expression parser and evaluator

[stormray]

Hello!

I would like to announce you RunFormula, my math expression parser and scripting engine for FreePascal and Lazarus.

Key features:

Supported
    integers in decimal, hexadecimal and binary formats;
    floating-point numbers in decimal and scientific notation;
    complex numbers and operations on them;
    intervals and operations on them;
    strings and ASCII characters;

Arithmetic and logical operations: + - * / or and xor not shl (<<) shr (>>) mod ( div == <> < <= >= > & (string concatenation) ** (integer exponentiation).
Variables and runtime initialization of variables via external callback function.
A set of built-in functions and the ability to register and use additional user-defined functions.
Control flow functions: if() repeat() exit() result() continue() break()
Ability to use inline function definitions directly within the formula (subroutines).
Support for the define directive.
Compiling the source formula into bytecode for multiple execution.
Minimal dependencies (only SysUtils in the base configuration).

Source code, Demo project, Help, Examples on GitHub:

https://github.com/runnfla/RunFormula

Any feedback are appreciated.

Hello stormray,
Welcome to the forum.

Nice, I like. I may need it someday, bookmarked.
Thank you for sharing it.

Version 0.0 is released. Added experimental support for physical dimensions, including unit consistency checks, automatic result dimensioning and automatic conversion between unit systems.

I just want to make a note: when generating commits, give them a meaningful name that helps understand the story (not a generic UPD)
