You can't.  There is no way that line of math can be *executed* without
compiling it (in a very broad sense of the word), so trying to do it with
no recompiles is futile.  Either you invoke the C compiler, or you write
a mini-compiler as part of your program.  *Something* has to turn the math
notation into an executable/interpretable representation of some kind.
