I'm trying to figure out my options for programming applications that require
floating point (80x87) calculations.  I'm currently using Actor 3.0, but that
doesn't have floating point support.  (Can anyone tell me whether Whitewater
plans to add floating point support?)  My applications, typically engineering
computations of phase and chemical equilibria, require solving systems of
nonlinear algebraic equations, which are numerically intensive. 

I'm further confused by my reading of Petzold, where (I'm trying to recall
from memory) he says that you can't use the floating point math library.  I see
that there's a DLL supplied which appears to be related to the math chip, but
how is one supposed to use it?  Are such topics covered in any detail in the
SDK manuals?  To be more specific, do I have any option other than getting the
SDK (I don't have it - I use Actor, as I've mentioned above) and trying to
implement my compute-intensive code as a DLL?  

My apologies if these are trivial questions, but not all applications can be
made to work with strings and integers!
