I may have something for you.
I wrote a real number expression evaluator in C and Pascal. You can
download them from my website (see below). From my home page, click
'Freeware' and then jump to 'Programmers Tools'.
Look for the C-library: JRFC01.ZIP or Pascal library: JRFPAS02.ZIP.
UnZip the file and then look for EVLLIB.
All the Best.
