Lommeregner funktion i C



Hej,

Jeg har ofte funderet på om der findes et bibliotek med en funktion der fungerer som en calculator.
Altså en funktion hvor argumentet er en tekststreng med et matematisk udtryk og returværdien er den beregnede værdi af udtrykket.
(Udtrykket skal beregnes run-time, da udtrykket ikke er kendt compile-time.)


fx.

y = calculate("2.5+3*8");
Hvor y så bliver 26.5

Licens: gerne LGPL, men ikke GPL.

Med venlig hilsen
Egon Andersen
