calculator

An expression parser and a virtual machine for Object Pascal. A formula compiles to a flat byte array and runs by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator turns that bytecode into machine code and hands back anything it declines, so an answer is never fast but wrong. 199 registered names, user functions and variables bound by address, symbolic differentiation. Depends on the RTL alone: no VCL, no FMX.

doctest is a new C++ testing framework but is by far the fastest both in compile times (by orders of magnitude) and runtime compared to other feature-rich alternatives. It brings the ability of compiled languages such as D / Rust / Nim to have tests written directly in the production code thanks to a fast, transparent and flexible test runner with a clean interface.
