Evex is a full-featured run-time expression evaluation library providing
a variety of built-in mathematical and string manipulation operators and
functions. A variable table is maintained for the storage and retrieval
of the results of evaluated expressions. New functions can be defined at
run-time using the #define built-in function and then subsequently
invoked. More complex or application-specific functions, or those
requiring higher, natively-compiled performance can be implemented as
part of the user's application and then registered as an Evex function.

Evex manual here:

http://sourceforge.net/projects/evex/files/evex/Evex_manual.txt/download

Evex is GMGPL licensed and is considered a Beta release, although there
are no known outstanding issues.

Evex requires Ada 2005, and time functions are GNAT-specific (though you
can omit that package if you don't need those capabilities).

Evex is built atop the example Ada expression parser from Dmitry
Kazakov's Simple Components collection
(http://www.dmitry-kazakov.de/ada/components.htm). Thanks Dmitry!
