ATMSP

A Tiny Mathematical Speed Parser

ATMSP is a portable C++ parser for mathematical expressions like “sin(x)+y^2” e.g. These may contain arbitrary numbers of functions, variables and constants. Major design goal was minimalistic size and maximum speed.

Tiny 320 code-lines offer a parser plus bytecode-generator, 26 mathematical functions and 17 supported base-types including complex and arbitrary MPFR-multiprecision. Both parser and bytecode may run in threads.

The usage of ATMSP is most simple – just include a single header in your own code and go. Reasonably experienced coders may implement other base-types like bool, SSE2, rationals or bigint’s with a few changes.
