will make it easy to handle fixed-point types.
Please, see this other post that discusses in more detail.
Here is a MATLAB example of converting to fixed-point and then back to double precision floating.
format long g
vOriginal = pi
vOriginal =
3.14159265358979
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 =
3.140625
