The assembler itself doesn't supply code for runtime floating point 
operation.  You can either find a library with the needed math routines or 
write your own.

Generally the easiest way to do this is to use a C compiler which comes 
with a library containing the functions you want.

What is the update rate for the wind tunnel?  You might need to use a 
faster processor, depending on the complexity of the calculations and the 
required update rate.
