fixed point modelling problem

hi

i m trying out fixed point modelling via the 'fi' function in matlab.
everything seems smooth until i tried to exponent the 'fi' object.
 
error msg: 'function exp is not defined for values of class
embedded.fi'
 
applying the exponential function, 'exp', is essiential for my
project. anyone knows how to get ard this prob?
 
cheers

Model the exponential that your fixed-point project will be using, and 
use it with the class embedded.fi.  Or cast the embedded.fi object to 
floating point and do an exponent on that -- but only if it accurately 
models what your embedded software's going to do.
