Yes, Fixed-Point Designer product makes it easy to handle fixed-point in MATLAB and Simulink.
will make it easy to handle fixed-point types.
Here is a MATLAB example of converting to fixed-point and then back to double precision floating.
format long g
vOriginal = pi
vOriginal =
vFi = fi(vOriginal,1,16,8)
vFi =
3.140625 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 8
vRoundTrip = double(vFi)
vRoundTrip =
