ExprTk is a C++ runtime mathematical expression parsing and evaluation engine, provided as an easy-to-integrate library. It supports arithmetic, logic, vector processing, control structures, loops, and expression optimization with high performance.

Use cases

• evaluate user-supplied math expressions at runtime in C++
• parse and evaluate formulas from config files
• build a calculator or expression evaluator app
• embed a small expression language in a scientific computing tool
• evaluate parameterized equations with variables and vectors
• implement a domain-specific formula DSL without writing a parser

When to choose

• you need fast, efficient runtime evaluation of mathematical expressions in C++
• you want a single-file, dependency-free library that is easy to integrate
• you need vector processing, control structures, and user-defined functions in expressions
• you want constant folding and other expression optimizations out of the box

When to avoid

• you need a general-purpose programming language interpreter rather than math expressions
• your project is not C++ or needs bindings for another language
• you need symbolic math or computer algebra rather than numeric evaluation
• you require a permissively licensed dependency and cannot accept the project's custom MIT-style notice
