HDL Coder: How to multiply floating point numbers in a stateflow project?

When I use HDL coder to produce code for the following simulink model (using the altera mega functions library), I get a complicated VHDL program that is able to handle floating points.

When I use HDL coder on the following stateflow model (again using the altera mega functions library)

I the floating point "variable" is just multiplied with the hexadecimal representation of a the floating point "1.1"

Multiplying two floating point numbers as if they were fixed point numbers obviously doesn't produce the correct result.

Is this a bug in stateflow or am I just not configuring HDL Coder correctly?

How can I solve this?

Note: I would like to avoid being restricted to fixed point numbers...

HDL Coder does not support Stateflow models with floating-point Math in actions. Please consider using MATLAB Function block with MALTAB data path architecture to model floating-point algorithms.
